How each side wins

From the forecast, the polls, the county map, voter groups, money and ballots
If you work for Troy Jackson
  1. Protect the lead

    Troy Jackson leads by 1.8 in the forecast and wins 65% of simulations. The cushion is about 13,205 votes; a one point swing is about 3,709 voters changing sides.

  2. The range

    In 8 of 10 simulations the result lands between R +5.1 and D +8.3. A normal polling error decides it.

  3. The polls

    The polls page average is D +2.8. Your best recent poll is University of New Hampshire at D +4.3; your worst is New York Times/Siena University at R +3.7. 15 polls in the last 30 days.

  4. Turn out the base

    The biggest vote banks for Democrats: Cumberland, a projected net 52,752 votes; York, a projected net 5,851 votes; Sagadahoc, a projected net 2,764 votes. Every point of extra turnout here is worth more than persuasion anywhere else.

  5. Win the battlegrounds

    The large counties within 12 points: York, D +5.0, 15.7% of the vote; Kennebec, R +6.8, 8.9% of the vote; Androscoggin, R +7.4, 7.1% of the vote; Hancock, D +6.6, 4.4% of the vote.

  6. Where you run behind the 2024 map

    Against the 2024 presidential vote, Troy Jackson runs furthest behind in Lincoln, Knox, Aroostook. That is where the forecast sees voters who backed your side two years ago and have not come back yet.

  7. The coalition levers

    Groups big enough to move the race: White voters, 94% of voters, 48 to 50, where a 5 point gain is worth 4.68 points; Voters who cast ballots in 2022 and 2024, 76% of voters, 53 to 45, where a 5 point gain is worth 3.81 points; Voters who find daily costs hard to afford, 60% of voters, 57 to 40, where a 5 point gain is worth 3.00 points.

  8. Where you lose ground

    The forecast's worst groups for Troy Jackson: Immigration voters 18 to 80, Men 43 to 55, 2024 nonvoters and third party voters 44 to 53. Cutting the loss here is often cheaper than winning new groups.

  9. The early vote

    Registered Democrats cast 50% of the 179,532 ballots in Maine so far, against 21% for the other party. That is 2.2 points better for Democrats than the forecast expected by now.

  10. What the ballots so far say

    The early vote has moved this forecast 0.3 points toward Troy Jackson. Bank it: chase the remaining mail ballots and low propensity voters who have not voted.

  11. Susan Collins's strongest asset

    Activity: 3 campaign stops by the candidate or surrogates in 30 days.

If you work for Susan Collins
  1. Close the gap

    Susan Collins trails by 1.8 and wins 35% of simulations. Closing it takes about 6,603 voters switching sides, or 13,205 more net votes from new turnout.

  2. The range

    In 8 of 10 simulations the result lands between D +8.3 and R +5.1. A normal polling error decides it.

  3. The polls

    The polls page average is D +2.8. Your best recent poll is New York Times/Siena University at R +3.7; your worst is University of New Hampshire at D +4.3. 15 polls in the last 30 days.

  4. Turn out the base

    The biggest vote banks for Republicans: Penobscot, a projected net 12,165 votes; Aroostook, a projected net 10,769 votes; Somerset, a projected net 7,292 votes. Every point of extra turnout here is worth more than persuasion anywhere else.

  5. Win the battlegrounds

    The large counties within 12 points: York, D +5.0, 15.7% of the vote; Kennebec, R +6.8, 8.9% of the vote; Androscoggin, R +7.4, 7.1% of the vote; Hancock, D +6.6, 4.4% of the vote.

  6. Where you run behind the 2024 map

    Against the 2024 presidential vote, Susan Collins runs furthest behind in Washington, Androscoggin, Somerset. That is where the forecast sees voters who backed your side two years ago and have not come back yet.

  7. The coalition levers

    Groups big enough to move the race: White voters, 94% of voters, 50 to 48, where a 5 point gain is worth 4.68 points; Voters who cast ballots in 2022 and 2024, 76% of voters, 45 to 53, where a 5 point gain is worth 3.81 points; Voters who find daily costs hard to afford, 60% of voters, 40 to 57, where a 5 point gain is worth 3.00 points.

  8. Where you lose ground

    The forecast's worst groups for Susan Collins: Health care and Social Security voters 31 to 67, Corruption voters 32 to 65, Large counties 34 to 64. Cutting the loss here is often cheaper than winning new groups.

  9. The early vote

    Registered Republicans cast 21% of the 179,532 ballots in Maine so far, against 50% for the other party. That is 2.2 points worse for Republicans than the forecast expected by now.

  10. What the ballots so far say

    The early vote has moved this forecast 0.3 points away from Susan Collins. Election Day has to make it up: the remaining vote must break harder your way than the forecast expects.

  11. Troy Jackson's strongest asset

    Activity: 16 campaign stops by the candidate or surrogates in 30 days.

Scouting report

From the Watchdog people files, each line with its source
Troy Jackson
  • Main message. A logger and union man who owes nothing to Trump or billionaires, running against Collins as a reliable Trump vote; he says Trump gets her vote "100% of the time" when he needs it. Source
  • Biggest vulnerability as opponents frame it. His Augusta record on electric rates and taxes, the mortgage residency question, late disclosure, and $138K in personal union consulting pay; Collins also notes his past opposition to abortion. Source
  • Strongest coalition. Independents, 52 to 45 in Marist October 1 to 4, and voters who say Trump's policies hurt Maine's economy or oppose tariffs, per CBS and YouGov. Source
  • Soft spot in the base. Four in ten Democrats wish someone else were the nominee, and Hannah Pingree runs ahead of him for governor. Source
  • Recent event. His "Oh, shut up" line at the final October 15 debate in Bangor; the Maine GOP called it unacceptable. Source

Top donor blocs: Small donors, Labor unions, Party and leadership

Susan Collins
  • Main message. Seniority and results: the Appropriations gavel, federal money for Maine, and a record of independence, citing her effort against Hegseth. Source
  • Biggest vulnerability as opponents frame it. That she gives Trump the votes he needs, "100% of the time" in Jackson's words, plus the Navatek pay to play allegation she denies. Source
  • Strongest coalition. Repeat Collins voters and state focused voters; she wins about one in five Trump disapprovers and holds enough Democrats to tie, per CBS News and YouGov, September 23 to October 1. Source
  • Recent event. At the final October 15 Bangor debate, Jackson told her "shut up" after she tied a protester to him; the Maine GOP called it unacceptable and she is using it in ads per a RedState headline not read. Source
  • Polls. Marist, October 1 to 4: Jackson 51, Collins 47 among registered voters; independents Jackson 52 to 45; 57 percent expect Collins to win. Source
