Collins is trying to fend off a challenge from Democrat Troy Jackson, a onetime state Senate president, and on Wednesday she made appearances with Joe Manchin, a West Virginian who became an independent late in his career before retiring.

After stopping for breakfast at Simones’ Hot Dog Stand in Lewiston, Collins spoke of how she and Manchin were “part of every piece of bipartisan legislation that passed and became law” during their time together in office.

Manchin said to lose Collins would be “to lose the soul of the Senate.” He praised her independent streak, her willingness to buck Republican President Donald Trump and her record of fighting for Maine’s interests.

“This is a true blue-blooded Maine person who knows exactly where she came from,” Manchin said.

They stopped later a New Balance shoe facility in Norway. Jackson, 58, is scheduled to campaign Thursday in Portland with Alexandria Ocasio-Cortez, the progressive congresswoman from New York.

Collins, 73, is in what may be her toughest reelection fight as she seeks her sixth term.

It’s only the second time that she’s sought reelection in a midterm with a sitting Republican president, and the national trends are much less favorable to the GOP than they were the last time she did so, in 2002. Trump’s approval has fallen well below where it was when he took office last year, and a recent poll from The Associated Press-NORC Center for Public Affairs Research found that a strong majority of voters want change in Washington.

‘We need more people like Susan Collins’

Collins has been working to persuade voters that she is independent of Trump and willing to break with him. In Manchin, she enlisted a politician who was one of the most moderate voices in the Senate. Manchin said in 2023 that Trump would “ destroy democracy in America” if he was elected to a second term.

Among the few dozen Collins supporters at the Lewiston event was Mike Marcotte.

“I may not have always been a fan of her complete package of votes, but when I look at the vitriol that’s in the U.S. Senate right now, we need more people like Susan Collins,” he said.

Jackson got a late start on campaigning after the party’s initial nominee existed the race, but trails Collins in the money race by less than $3 million after an aggressive quarter in which he raised more than $20 million. Jackson has campaigned relentlessly and his events have drawn hundreds. Collins has largely stuck to smaller appearances.

Some of Jackson’s backers demonstrated across the street from the hot dog stand. A few held signs bearing the face of Brett Kavanaugh, the U.S. Supreme Court justice whom Collins voted to confirm and whose vote eventually helped overturn the constitutional right to abortion.

“Someone needs to stand up and be a check on Donald Trump and his harmful policies,” said David Sysko.

Collins’ loyalty to Trump has been a central focus of the race

Collins has broken with Trump and Republicans over the years. She voted to convict him at his impeachment trial in 2021. Increasingly during the campaign, she has worked to distance herself from the president as Democrats argue that she is too close to him.

Collins said in early October that she is “not exactly his favorite senator,” and that she did not expect Trump to campaign in Maine. He has steered clear of the state with the Nov. 3 election nearing.

Pinning Collins to Trump is central to the Democrats’ strategy. In one ad, a nurse says the state is in a healthcare crisis “because of Susan Collins and Donald Trump,” citing Collins’ vote for Trump’s push for Medicaid cuts. Collins did vote to advance the bill, but ultimately voted against it.

Trump also was a major focus of four contentious debates between the candidates this month, where Collins sought to distance herself from the president and Jackson repeatedly accused her of doing Trump’s bidding.

Asked at the final debate to name a time in which she bucked her own party and succeeded, Collins gave the example of rallying support against Trump’s nomination of Pete Hegseth, who was confirmed as defense secretary.

Democrats seized on the moment and released a statement that said the exchange “underscores a central question in the Maine Senate race: Does Collins, a Republican in a state that disapproves of President Donald Trump and has grown bluer in recent years, stand up to her party enough to earn the independent streak she has staked her career on?”

Jackson has characterized Collins as out of touch with the struggles of working-class people in Maine. He has described Collins as a “rubber stamp” for the president and criticized her votes on Kavanaugh and Robert F. Kennedy Jr., Trump’s second-term health secretary. Collins has said she does not regret either vote.

Republicans have cast Jackson as a bully

Republican ads against Jackson, a logger from northern Maine, have focused more on accusations of his having a volatile personality and behaving like a bully with female colleagues. Jackson has denied those accusations.

Collins distanced herself on Wednesday from a Republican super PAC attack ad that she said “should be taken down.”

The senator was a top target of Democrats in 2020 when she defeated challenger Sara Gideon by nearly 9 percentage points. Collins is the only Republican senator from New England, a distinction she has had since January 2013.
