2026 Maine Senate Race
Coverage from Action Network, Trending Politics, and others
The 2026 Maine Senate race is a contest between Democratic nominee Troy Jackson and Republican incumbent Susan Collins.
CNN/SSRS polling reported Jackson ahead by 48% to 45%, a result within the survey’s margin of error, while many voters remained uncommitted or unfamiliar with Jackson. Voters’ economic concerns, including the cost of living and tariffs, figure prominently alongside views on Donald Trump and abortion rights after the Dobbs ruling. The race brings together candidate evaluations, partisan sentiment and questions about which issues will matter most to Maine voters.

If you read one thing
This broad overview introduces the close Jackson–Collins contest and the economic and national political concerns shaping it.
Best explainer
Its poll findings connect economic concerns and views of Collins to the motivations behind each candidate’s support.
The evidence
The Marist results add a distinct, recent poll showing how likely-voter turnout leaves the race statistically unresolved.
Key Issues
A statistically unresolved polling contest
Recent polls show Jackson narrowly ahead or the candidates tied, with leads generally within sampling error. Different samples and turnout patterns leave the contest without a clear polling leader; the new evidence reinforces the close, stable picture.
Stable
Voter choices center on Collins more than Jackson
Available polling suggests many voters’ choices are driven more by views of Collins than by Jackson personally. Jackson’s support is often described as opposition to Collins, while Collins also retains personally motivated support.
Stable
Trump alignment is a liability, but not a complete break
Polls report substantial concern that Collins aligns too closely with Trump, making the association a potential vulnerability. She nevertheless draws some support from Trump-disapproving voters, so the liability is not absolute.
Stable
Economic strain remains a salient voter concern
Survey evidence identifies economic pressure as a leading concern and reports many voters feel worse off than two years earlier. Campaign messaging points to local industry support and tariff relief, but the available evidence does not establish that these measures have shifted candidate support.
Stable
Key Numbers
45% percent
likely voters supporting Susan Collins
“In Maine, 48% of likely voters back Jackson and 45% support Collins. The result is within the survey's margin of sampling error.”
49% percent
likely voters supporting Troy Jackson
“Despite those views, Collins and Jackson are tied at 49%. All survey interviews were completed after the candidates’ Oct. 15 debate.”
783 likely voters
Maine poll sample size
“The CNN polls of likely voters were conducted online and by telephone from Oct. 20-27, 2026 in Michigan and Texas and Oct. 20-26, 2026 in Kansas and Maine. Registered voters were randomly sampled from both registered voter lists and a probability-based panel. Results among likely voters include all registered voters in the poll weighted for their predicted likelihood of voting in this year's election. Results among the 838 likely voters in Kansas have a margin of sampling error of plus or minus 4.5 percentage points; among the 783 likely voters in Maine, the margin of sampling error is 4.5 percentage points; among the 768 likely voters in Michigan it is 4.7 percentage points, and among the 923 likely voters in Texas it is 4.2 percentage points.”
4.5 points
Poll margin of error
“The CNN/SSRS Kansas poll was conducted from Oct. 20-27 among 783 likely voters in Maine and 838 likely voters in Kansas. The polls have a margin of error of 4.5 points.”
619 voters
Maine voters surveyed
“Among 619 Maine voters surveyed Sept. 15-22, 49% said they were likely to vote for Collins and 46% for Jackson. The result is Jackson’s weakest in a public poll since he entered the race in July. A separate UMass Lowell/YouGov poll, published Sept. 24 and conducted Aug. 28-Sept. 14, showed Jackson leading by five points.”

The Story So Far
No material change
The new reports add another poll showing Jackson narrowly ahead of Collins, but the lead remains within sampling error and does not materially change the assessment of a close, uncertain race.
Previously
Late-October polling puts Democrat Troy Jackson slightly ahead of Republican incumbent Susan Collins, but the reported margins fall within sampling error and forecasts describe the contest as a toss-up. A separate Marist poll also finds a narrow Jackson lead, while voter assessments of Collins, candidate favorability, turnout motivation, advertising exposure, and economic concerns add context to the close race. Most of the apparent volume comes from republication of the same CNN/SSRS survey rather than independent polls.
History
11/01/2026
A newly included Data for Progress poll adds another narrow Jackson lead, while CNN/SSRS comparisons suggest little movement since late summer. The added evidence reinforces the race’s close, stable polling picture rather than changing its interpretation.
10/31/2026
A newly prominent CNN/SSRS poll puts Jackson four points ahead, still within sampling error. Added survey details reveal different supporter motivations and greater exposure to pro-Collins advertising, while repeated republication means the poll volume is not independent corroboration.
