Sen. Susan Collins, R-Maine, and Democratic challenger Troy Jackson collided over wealthy campaign donors, party loyalty, and working-class voters during their fourth debate Thursday night. The Oct. 8 encounter grew increasingly personal as both candidates challenged the other's independence and credibility.

Collins pressed Jackson near the beginning of the debate about his campaign promises to reject billionaire donors closely aligned with Democratic campaigns. She pointed to Federal Election Commission contribution records that appeared to conflict with those assurances.

"And as far as the billionaires that I might have on my campaign, that is accurate," Jackson admitted. Members of the crowd responded audibly as Jackson paused following the admission.

"I haven’t made any deals like Senator Collins has with those billionaires," Jackson continued. "I’m going to tax those billionaires when I get to the U.S. Senate."

Wait. Troy Jackson has self-righteously said he doesn’t take billionaire $, but now admits that he has [but that’s (D)ifferent]…and also claims he has no control over an ad he narrates on camera & *literally says he approved,* in the ad itself?

Jackson did not identify the agreements he accused Collins of making. The exchange put campaign funding squarely at the center of a debate already loaded with questions about political loyalty.

Collins also faced scrutiny over her independence from President Donald Trump. A moderator asked her to identify an instance when she had defied the president and changed the outcome of a decision.

The senator cited her opposition to the confirmation of War Secretary Pete Hegseth, who faced scrutiny during his nomination concerning his qualifications and allegations about his personal conduct. Collins said she had attempted to organize enough opposition to stop his confirmation.

"At one point, I had organized people to vote against Secretary Hegseth. As you undoubtedly have read, at the very last minute, one of our Republicans changed his mind. Otherwise, he would have been defeated for that job," Collins said.

Jackson quickly noted that Hegseth was ultimately confirmed despite Collins' opposition. He argued that her record showed she still backed Trump when her vote mattered most.

"Senator Collins likes to have it both ways. I mean, the reality is that 100% of the time when Donald Trump needs her, Susan Collins is going to be there. That has happened time and time again," Jackson said.

Collins responded by describing what she called a "major difference between Troy and me. I vote very independently ... I am the most bipartisan member of the Senate." Referring directly to Jackson, she added, "We don’t need more people who are going to vote a straight party line."

Jackson defended his independence by pointing to disputes with Democratic Maine Gov. Janet Mills during his time in the state Senate. "How can I be a rubber stamp with my very own governor — a Democratic governor — vetoing 40 of my bills?" Jackson asked.

The candidates also revisited Jackson's repeated claims during their three earlier debates about how frequently Collins voted with Trump. Collins argued that Jackson relied on a limited share of votes to make his case.

"You have heard Troy say that I vote with the president 92 or 94% of the time; that takes only a third of the votes. If you look at 90% of the votes, you will find that I vote with him 72% of the time, not 95% of the time," Collins said.

The sharpest personal exchange arrived near the end, when Jackson, a former logger, questioned whether Collins looked down on him because of his working-class background. "And so, I guess, you know, what I'm curious about — is it just me that you look down on, or is it working-class people overall?" he asked.

Collins firmly rejected that charge and invoked her own upbringing in Caribou. "Troy, I do not look down on you or on anyone. I grew up in Caribou. My first job was picking potatoes," Collins said.

She continued, "I have worked since I was age ten, literally since I was age ten. I have enormous respect for all the people of Maine."

Collins, the Republican incumbent, and Jackson, a former Maine Senate president and the Democratic nominee for U.S. Senate, entered the campaign's closing stretch after the debate. Maine's general election is scheduled for Nov. 3, with control of the U.S. Senate at stake.
