Maine Senate Race Stalls at Deadlock as Collins Holds Ground Despite National Headwinds

Key points

• The CBS News/YouGov poll, conducted Sept. 23–Oct. 1, 2026, finds the race tied, with Collins holding her ground in a state that leans Democratic.
• Collins attracts nearly one in five voters who disapprove of President Trump, a higher rate than typical Republican candidates nationally.
• Jackson’s support is driven by voters opposed to tariffs, those seeking national Democratic control of the Senate, and those prioritizing change over experience.
• Despite economic concerns, Collins retains support among voters who believe her policies would benefit them financially, and among repeat voters.
• Jackson trails the state’s gubernatorial nominee, Hannah Pingree, and faces criticism from 40% of Democrats and most independents who wish for a different nominee.

Background

This race has been closely watched since August, with earlier polls showing Collins with a narrow 3-point lead before recent allegations surfaced. CNN polls in September indicated the race was tightening to near parity, with economic issues and Trump’s unpopularity driving voter sentiment. The current CBS poll reflects a shift to a dead heat, suggesting the race may break either way.

How outlets are covering it

CBS News emphasizes the split between state and national focus, noting Collins’ ability to peel off Trump-disapproving voters. The Washington Post highlights a contradiction in Jackson’s campaign, noting he previously ran a PAC that courted special interests despite his current anti-corporate messaging. A letter to the editor in CentralMaine.com criticizes Jackson for reversing positions on Gaza and universal healthcare, suggesting a loss of passion. Charlie Cook, via Yahoo, argues Collins is now the favorite, contradicting the CBS tie finding.

Why it matters

Maine is a pivotal state for Senate control, and the outcome could influence the balance of power in the 119th Congress. The race also reflects broader tensions between national party strategy and local voter priorities, with implications for how Democrats approach other competitive states.

What to watch

With 10% of voters undecided, the race could break either way in the final weeks. Campaigns will likely intensify efforts to sway undecided voters and address economic concerns. The outcome of the gubernatorial race, where Hannah Pingree leads, may also influence Senate voter behavior.
