The forecast

The prediction
About the prediction: a forecast for the Maine U.S. Senate race built on five bellwether towns: polls and early voting now, official results on election night. The number is its margin, in points. Before election night it follows the polls; once results post, the five bellwether towns take over. The needle points to the leader; the dark arc is the likely range. Maine counts U.S. Senate ballots by ranked-choice voting: if no candidate has more than half the first choices, the last-place candidate is dropped and those ballots count for their next choice, round by round. This page forecasts the first count, which decides the race when only two candidates are on the ballot. Margins are in percentage points: "Jackson +3" means Jackson leads by 3.

I'm Maren Holt, and this is your Pollitrack digest on the Senate race in Maine.

On November 3, Maine decides who holds this seat for the next six years. On the ballot, in the order Maine lists them: Republican Susan Collins, the senator, seeking another term, and Democrat Troy Jackson, a logger from Allagash and a former president of the state Senate.

The polling average has Jackson ahead by 1.4 points across ten recent polls. Pollitrack's forecast takes 2 points off Jackson's side, because Maine polls have understated Republicans in several recent races, Collins's own race in 2020 most of all, and it adjusts a little for the early vote. That puts Collins ahead by 0.1, with a 51 percent chance of finishing first and Jackson at 49 percent.

In other words, a coin flip. Either candidate could finish ahead.

Absentee voting runs through October 29. So far, about 175 thousand Mainers have voted. That is 140 percent of the 2022 midterm at the same point, and 84 percent of the 2024 presidential pace.

A big early vote does not tell us who is ahead. It tells us interest is high on both sides.

On election night, Pollitrack reads five bellwether towns, each standing in for a part of the state: Portland for the coast, Winthrop, the town that has tracked the state most closely, Berwick for the southern commuter towns, Poland for rural and small-town Maine, and Old Town for Bangor and the north.

Polls close at 8 pm Eastern. Maine counts Senate races by ranked choice: if no one passes half of the first choices, the later rounds are counted in Augusta over the following days, and this page shows the first round. Scroll down to explore each town, or switch to What-if mode and play out your own night. I'm Maren Holt. See you on election night.

Now

Early voting
How to read this: the line adds up early votes day by day, in person and by mail. The amber line is 2026; the gray lines are past years on the same day of early voting, so a 2026 line above them means more early votes than then. Refreshed every morning and afternoon from the Maine Secretary of State's absentee voter file.

How to read this: each bar is one town group's early votes as a share of 2024 at the same point; the black tick is Maine overall, so a bar past the tick means that group is voting early faster than the state.

Five town groups
How to read this: every town joins the group whose bellwether town it has moved most like since 2016. The color is the group's margin in the view you pick: where its bellwether lands if the polls are right, its 2024 President result, or, on election night, how far each town has shifted since 2024. Darker means a bigger lead: 15 points or more, 5 to 15, or under 5. Tap a group or a town to light up its group.

500 possible election nights
How to read this: the forecast is replayed 500 times, each with a different random draw of its uncertainty. Each dot is five possible nights, stacked by the statewide margin in 1-point steps: blue dots are Jackson wins and red dots are Collins wins. The more dots on one side of the tie line, the likelier that candidate wins.

Trade-off
How to read this: pick two town groups. Left to right is one bellwether town's margin and bottom to top is another's, with the other three groups held where they are now. Each square is colored by the statewide result: blue squares are Jackson wins and red squares are Collins wins, darker for a bigger win. The black line is a statewide tie, and the amber dot is where things stand now. Hover a square for its numbers.

The five bellwethers
How to read this: each row is one town, on a scale from a big Collins lead (left) to a big Jackson lead (right). The amber mark is the tie line: if every part of Maine shifted as much as this town did, a result there would mean a statewide tie. A dot to the right of it is good news for Jackson, and to the left for Collins; the colored bar shows how far each town is from the tie line, and toward whom. The gray ticks are the 2024 and 2020 results. The dot is where the polling average points until results post, then the real result. Drag a dot, tap anywhere on a row, or use the arrow keys to try your own numbers; the dot clicks onto the marks when you get close.

Which parts of Maine turn out
How much of the statewide vote each town group casts. The early-voting option tends to favor the cities, since rural Republicans often vote later or on Election Day.
Applies to towns that have counted only early votes so far, and shrinks as their Election Day votes come in. Maine doesn't publish past results by vote type, so this setting is the whole adjustment. Republicans say they're likelier to vote on Election Day this year.
How unsure the forecast stays even after all five towns finish counting. The default, 1.5 points, is wider than this method's typical miss on past races, because a new race can break from old patterns.
Taken off the polling average until results post. Maine's final poll averages, taken the way this page takes them, missed Collins by 11.4 points in 2020; the 2020 and 2024 presidential averages leaned Democratic by 3.5 to 4, the 2018 governor's average by half a point, and the 2022 governor's average leaned Republican by 3.5. Maine's own average is 3.1 points; the default of 2 points is that average pooled with the other states' midterm-year misses, which have run about half a point. The next setting adjusts it for this year's early vote.
The "Where early votes are coming from" number above, times this weight, comes off the allowance when early votes are coming from more Democratic places than at this point in 2024 and goes onto it when they come from more Republican places. It is 0 by default: in 2022 and 2024, measured against the election two years earlier, that lean did not predict how the polls missed. Turnout level alone doesn't say which way polls will miss either: 2018's record midterm turnout broke toward Democrats, 2020's and 2024's broke toward Republicans. The places voting drift toward the Democrat late, not the Republican: big urban towns cast their in-person early votes last, so the mix of places voting moved 0.2 to 1.9 points toward Democratic places over the final eleven days in 2022 and 2024.

Why each town was picked and what to watch.

Portland and coast test
Portland
Tie line: Jackson +58.4 · the biggest group, and where Collins's crossover votes count most
2024 President
Harris +64.9
2020 Senate
Gideon +46.7
2022 Governor
Mills +71.3
Compared with Maine
54–58 points more Democratic, every race since 2016

Why this town

Portland casts about one in twenty Maine votes (39,336 in 2024), and its gap with the state has held steady: 54 to 58 points more Democratic in every race since 2016. Its group of 54 towns (South Portland, Scarborough, Brunswick, Saco, Biddeford, Westbrook and most of the southern coast) casts 30% of the statewide vote, more than any other group, and Harris won it by 41. It's also where Collins found the most crossover votes: in 2020 Biden won the group by 41.1 while Gideon won it by only 20.8, a 20-point gap, compared with 17.7 points statewide.

What to look for

The tie line here is Jackson +58: a result above it favors Jackson, below it Collins. Harris won it by 64.9 and won Maine by 7; Gideon won it by 46.7 and lost Maine by 8.6. A Jackson margin in the 60s means Collins is drawing few crossover votes, and Jackson is probably ahead. A margin in the low 50s means she is drawing many, and Collins is probably ahead. South Portland (tie line Jackson +44.9) is a good second check.

When results come in

Maine has no live state results feed, so on election night this page stays on the polls until the Secretary of State posts its town-by-town spreadsheet, likely weeks later. The Bangor Daily News (with Decision Desk HQ) and the Associated Press collect Portland's count from the city clerk that night. To use it, switch to What-if mode and set Portland to that margin. Half of Portland's 2024 votes were absentee ballots (19,805), which can't be tallied until polls close at 8, so big cities can take a while. In 2020 Kittery, in this group, had its count Tuesday night but sent it in Wednesday morning.

Signals so far

South Portland: . Maine overall: . As of October 19 this group's towns together were 8% behind 2024's pace, the closest of any group; the rural group was 28% behind. Enrolled Democrats cast 71% of Portland's returned absentee ballots and Republicans 6%, compared with 66% and 9% of all its absentee ballots in 2024. Bernie Sanders rallied with Jackson in Biddeford on October 11.

Best overall predictor
Winthrop
Tie line: Collins +1.8 · the town that has tracked Maine most closely
2024 President
Harris +4.7
2020 Senate
Collins +10.6
2022 Governor
Mills +11.3
Compared with Maine
0.1–1.8 points more Republican, every race since 2016

Why this town

No Maine town has tracked the statewide result more closely. Winthrop, a Kennebec County lake town of about 3,900 voters just west of Augusta, has voted between 0.1 and 1.8 points more Republican than Maine in every statewide race since 2016. Add a point to its margin and you'd never have missed the statewide result by more than 0.9 points. In the last three races it sat at the more Republican end of that range. Its group of 97 towns, including Lewiston, Sanford, Augusta, Waterville, Brewer and Ellsworth, casts 23% of the statewide vote and split almost exactly evenly in 2024 (Harris +0.5).

What to look for

The tie line here is Collins +1.8: a wider Collins margin favors Collins, a narrower one Jackson. Harris won it by 4.7 and Maine by 7; Collins won it by 10.6 in 2020 and Maine by 8.6; Mills won it by 11.3 in 2022. If Jackson carries Winthrop, he's probably ahead statewide; if Collins wins it by 5 or more, she probably is. Augusta, the capital, is a bigger stand-in in the same group (tie line Jackson +3.4).

When results come in

Like every Maine town, Winthrop reports to news outlets on election night, not to a live state feed, so this page won't have its count until the Secretary of State's spreadsheet posts. If you're following along, set Winthrop in What-if mode to the margin the Bangor Daily News or the Associated Press reports. About half of its 2024 votes (1,969) were absentee ballots. Its result arrives complete: Maine reports no split between absentee and Election Day votes, so there's no early number that later moves.

Signals so far

Lewiston, the group's biggest city: . Augusta: . As of October 19, enrolled Democrats cast 47% of Winthrop's returned absentee ballots and Republicans 24%, compared with 37% and 32% of all its absentee ballots in 2024. Sanders and Jackson held a rally in Lewiston on October 11.

Southern exurbs test
Berwick
Tie line: Collins +12.9 · commuter towns where Collins ran least far ahead of Trump
2024 President
Trump +6.4
2020 Senate
Collins +18.4
2022 Governor
Mills +0.2
Compared with Maine
9–17 points more Republican since 2016

Why this town

Berwick, a York County town on the New Hampshire line, leads 61 towns in the commuter belt around Portland and Lewiston: Auburn, Windham, Standish, Gray, Buxton, Lisbon and the southern lake towns. They cast 15% of the statewide vote and split nearly evenly in 2024 (Trump +1.9). Berwick has moved toward Democrats, from Trump +14.0 in 2016 to Trump +6.4 in 2024. It's also where Collins's personal vote was thinnest: in 2020 she ran 13 points ahead of Trump in Berwick, compared with 17.7 statewide. Of the five bellwethers it's one of the noisier stand-ins, so check Lisbon too.

What to look for

The tie line here is Collins +12.9: a wider Collins margin favors Collins, a narrower one Jackson. Trump won it by 6.4 in 2024 while losing Maine by 7; Collins won it by 18.4 in 2020; Mills carried it by 0.2 in 2022. At Collins +15 or more, she's probably ahead; under 10, Jackson probably is. Lisbon's tie line is Collins +17.3.

When results come in

Not on this page until the Secretary of State's spreadsheet posts; on the night, Berwick's clerk reports to the news media. Towns that filed notice may open and check absentee ballots from October 27, seven days before Election Day, but nobody may tally them until polls close. In 2024, 37% of Berwick's votes (1,730) were absentee ballots. Clerks then have two days to send their unofficial count to the Secretary of State.

Signals so far

Auburn, the group's biggest city: . Windham: . As of October 19, enrolled Democrats cast 42% of Berwick's returned absentee ballots and Republicans 24%, compared with 34% and 27% in 2024. Unenrolled voters cast a third, more than in most of Maine.

Rural Maine test
Poland
Tie line: Collins +19.4 · stands in for 154 small towns, from the western lakes to Presque Isle
2024 President
Trump +12.9
2020 Senate
Collins +28.7
2022 Governor
LePage +7.9
Compared with Maine
17–21 points more Republican, every race since 2016

Why this town

Poland, an Androscoggin County lake town (the Poland Spring of the bottled water), leads the group with the most towns: 154 rural and small-town places, including Presque Isle, Hermon, Turner, Sidney and Hollis, casting 18% of the statewide vote. Trump won the group by 24 in 2024 and Collins by 37 in 2020. Poland has voted 17 to 21 points more Republican than Maine in every race since 2016, so it's a steady read on rural Maine. Every point of swing here is worth about a fifth of a point statewide. Jackson is a fifth-generation logger from Allagash, near the Canadian border, and this group tests whether that plays in rural Maine.

What to look for

The tie line here is Collins +19.4: a wider Collins margin favors Collins, a narrower one Jackson. Trump won it by 12.9 in 2024; Collins won it by 28.7 in 2020; LePage won it by 7.9 in 2022 even while losing Maine by 13. A Collins margin in the high 20s, like 2020, means she is probably ahead; well under 20, Jackson probably is.

When results come in

Not on this page until the Secretary of State's spreadsheet posts. Poland is big enough to count by scanner, but about 150 Maine towns, all with fewer than 750 registered voters, count by hand, with two clerks tallying each race and checking that their sheets match. Many of them are in this group (58 of its towns cast fewer than 500 votes in 2024), so the rural picture in news outlets' counts fills in late in the night and into Wednesday.

Signals so far

Presque Isle: . As of October 19 this group's towns were 28% behind 2024's pace, though rural mail ballots tend to come back late. Enrolled Democrats cast 42% of Poland's returned absentee ballots and Republicans 27%, compared with 32% and 35% in 2024.

Northern Maine test
Old Town
Tie line: Jackson +6.1 · both candidates' home ground, from Bangor to the St. John Valley
2024 President
Harris +12.7
2020 Senate
Collins +5.7
2022 Governor
Mills +21.3
Compared with Maine
3–10 points more Democratic since 2016

Why this town

Old Town, a Penobscot River city just north of Bangor, leads 117 towns across central and northern Maine: Bangor, Skowhegan, Farmington, Caribou, Houlton, Millinocket, Fort Kent and Madawaska. They cast 14% of the statewide vote; Trump won them by 10.8 in 2024. The candidates' roots meet here. Collins grew up in Caribou and lives in Bangor; Jackson was born in Fort Kent and lives in Allagash. In 2020 Biden lost this group by 6.8 while Gideon lost it by 25.2; in Caribou, Biden lost by 13.9 and Gideon by 46.2. Old Town is the least precise of the five bellwethers, so Bangor is worth a look too.

What to look for

The tie line here is Jackson +6: a result above it favors Jackson, below it Collins. Harris won it by 12.7; Collins won it by 5.7 in 2020; Mills won it by 21.3 in 2022. If Collins carries Old Town again, she's very likely ahead statewide; if Jackson wins it by Harris's 12.7 or more, he very likely is. In Bangor the tie line is Jackson +13.1; Gideon lost Bangor by 0.6. Old Town is also home to Matt Dunlap, the Democratic nominee for the open 2nd District House seat against Paul LePage.

When results come in

Not on this page until the Secretary of State's spreadsheet posts; on the night, clerks here report to the Bangor Daily News and the Associated Press. Northern Maine can be slow. In 2020 the Associated Press called the 2nd District for Trump early Wednesday afternoon and the Senate race for Collins around the same time, with about 95% of the vote counted.

Signals so far

Bangor: . Caribou: . As of October 19 this group's towns were 30% behind 2024's pace, the furthest behind of the five. Enrolled Democrats cast 55% of Old Town's returned absentee ballots and Republicans 20%, compared with 46% and 25% in 2024. Sanders drew more than 600 people to a rally for Jackson in Bangor on October 10.

Timeline

When results usually arrive, Eastern time.

Oct 5–Nov 3

Absentee voting. Maine's early voting is absentee voting: in person at the town office through October 29 (also the last day to ask for a ballot), or by mail or drop box until polls close at 8 pm on Election Day. The tracker above counts returned ballots by town and party from the Secretary of State's file, a day behind. Through October 19, 127,000 had come back, 17% fewer than at this point in 2024 but 37% more than in 2022. Enrolled Democrats cast 53% of them and Republicans 20%; in 2024's final absentee count it was 42% and 28%.

Nov 3 · 8:00 pm

Polls close everywhere in Maine; towns start counting. Towns that gave notice could open and check absentee ballots from October 27, but nobody may tally them before now. About 150 small towns count by hand; the other 330 or so, including all five bellwethers, use scanners. There is no live state results feed. Clerks report their counts to the Bangor Daily News (with Decision Desk HQ) and the Associated Press, and some post their own. This page doesn't read those, so its forecast stays on the polls tonight. To try a town's real number, switch to What-if mode and set that bellwether to the margin the news reports.

9:00 pm–midnight

Towns report to news outlets; the page is still on the polls. Clerks report first choices only. A town's count arrives all at once, since Maine doesn't report absentee and Election Day votes separately, so a bellwether's margin can go straight into What-if mode. Big towns with many absentee ballots, such as Portland, where half of 2024's votes were absentee, can take longer. Decision Desk HQ and the Associated Press project a winner only when the result is nearly certain not to change.

Wednesday

The last towns report. In 2020 some towns sent their counts Wednesday morning and the count ran most of the day. Gideon conceded and the Associated Press called the race for Collins early Wednesday afternoon, with about 95% counted. Clerks have two days to send their unofficial results to the Secretary of State. If the race is within a point or two of 50%, the next step may decide it.

Nov 5–13

A ranked-choice count in Augusta, if no one has a majority. With only two names on the ballot, a second round happens only if blank ballots and write-ins (six declared write-in candidates this year) keep the leader under half of the first-round ballots. That happened in the 2024 2nd District race: Golden had 48.65% and Theriault 48.11%, so the Secretary of State gathered the ballot records in Augusta, started the count on November 12 and announced the winner on November 15, ten days after the election. This page shows the first-round margin and doesn't model later rounds. A losing candidate has five business days to ask for a recount.

Mid to late November

The Secretary of State's spreadsheet posts; the page switches to results. The state has 20 days to certify the count, which means by November 23. In 2024 the town-by-town U.S. Senate spreadsheet was posted by November 26, with a corrected version on December 5. Once it posts, the page reads every town's first-round count at once and real results replace the polls.
