Polls show a close contest between Republican incumbent Susan Collins and Democrat Troy Jackson, but do not establish a consistent leader: a CNN-SSRS survey put Jackson ahead by three points within its margin of error, while later polls ranged from a Collins lead to a Jackson lead.
Economic conditions and cost of living rank prominently among voter concerns, alongside views on tariffs and abortion. The mixed polling leaves the state of the contest uncertain rather than pointing to a clear shift in either candidate’s standing.
It adds concrete evidence on tariff concerns and distinguishes polling among likely voters from registered voters.

Key Issues
01
No clear polling leader
Recent surveys continue to put the candidates within a few points, with some favoring Jackson and others Collins. The differing results and polling margins do not establish a dependable advantage for either candidate.

02
Trump alignment weighs on Collins
Broad disapproval of Trump and opposition to his agenda create a difficult political environment for Collins, while Jackson’s support draws heavily on opposition to the incumbent and her relationship with Trump. This pressure has not translated into a decisive polling break.

03
Affordability and tariffs shape voter concerns
Economic and cost-of-living concerns rank among voters’ leading issues, and surveys find widespread concern that tariffs on Canadian goods will hurt Maine. This creates a potential liability for Collins, though she has also criticized the tariffs.

Collins’s advantages meet a tighter crossover path
Collins retains incumbency, greater familiarity, and a record of attracting crossover voters, but reporting describes a narrower Democratic and independent coalition for her. Jackson is seeking to capitalize on former Collins supporters’ concerns about Trump and her record.

The Story So Far
No material change
New polling continues to show a close, statistically unresolved contest, with surveys split over whether Jackson or Collins is ahead; it does not materially change the picture established in the prior state.
Previously
Maine’s 2026 Senate race is effectively tied: Troy Jackson holds a small but inconsistent polling edge over Susan Collins, while economic pressure, Donald Trump’s unpopularity, and Collins’s crossover strength shape the contest.
History
09/19/2026
