Republican Sen. Susan Collins and Democratic challenger Troy Jackson faced off Tuesday in their first debate of Maine's Senate race, clashing over President Donald Trump, abortion, immigration enforcement and the cost of living, according to NBC News and CBS News.
The contest is considered one of the most closely watched Senate races in the country, with both parties pouring tens of millions of dollars into the race, NBC News reported. Polls show a tight race between the two candidates, often within the margin of error.
Jackson repeatedly tied Collins to Trump throughout the debate, invoking the president's name at least 20 times over the hour-long exchange on WGME-TV, according to NBC News. He said Collins votes in line with Trump 96% of the time, citing a study whose methodology Collins questioned.
Collins pushed back by highlighting instances where she broke with the administration, including her vote against what CBS News described as the Trump-backed One Big Beautiful Bill Act and her support for restricting Trump's authority to wage war against Iran. She also dodged questions about whether she would appear alongside Trump if he visited Maine, saying she had heard nothing from his office and adding, “I'm not exactly his favorite senator,” according to both outlets.
Jackson argued that despite her seniority, Collins has not used her influence to effectively challenge the president's policies. Collins, in turn, emphasized her role as chair of the Senate Appropriations Committee, saying her experience and relationships in Washington have let her secure federal funding for Maine.
Jackson criticized Collins' 2018 vote to confirm Supreme Court Justice Brett Kavanaugh, who was part of the majority that later overturned Roe v. Wade. Collins said she evaluates nominees based on qualifications and noted she also supported justices nominated by Democratic presidents who voted to uphold Roe. She also pointed to Jackson's past opposition to abortion earlier in his career, saying only she has consistently held a pro-choice position.
On the One Big Beautiful Bill Act, Jackson criticized Collins for voting to advance the legislation procedurally even though she ultimately voted against its final passage. Collins said that by allowing the bill to proceed, she was able to secure a $50 billion fund for rural hospitals, while opposing its Medicaid cuts. Jackson compared her position to an arsonist seeking credit for helping put out a fire he helped start.
Both candidates criticized the conduct of Immigration and Customs Enforcement following the killing of a man in Maine by an ICE officer during a traffic stop over the summer, which Collins called “horrific.” But they differed on the response: Jackson called for ICE to be disbanded and said it should not have received additional funding, while Collins said the agency needs serious reform but should continue to exist.
The outcome in Maine could help determine which party controls the Senate, a chamber that shapes federal spending, judicial confirmations and oversight of the Trump administration. Collins is the only Republican senator representing a state Trump lost in 2024, making her race a key test of whether an incumbent with deep ties to federal funding decisions can hold a seat in a state that leans Democratic.
For Maine residents, the debate highlighted disputes over Medicaid funding, hospital support, energy costs and trade policy toward Canada, all of which affect local prices and services. The candidates' differing approaches to immigration enforcement also reflect broader national debates over ICE's role and oversight following the killing of a Maine resident by an ICE officer.
