For decades, Susan Collins survived in a state that often rejected her party by convincing Democrats and independents that she was different.

She was moderate.

She was independent.

She was willing to stand up to Republican presidents when the moment demanded it.

Now, with control of the United States Senate potentially hanging on her Maine seat, some of the voters who sustained that reputation say they have finally had enough.

“I just gave her the benefit of the doubt,” Democrat Kim Bridgham told the Washington Post.

Then came the vote that ended it.

“When she voted for RFK Jr., I totally lost it.”

Bridgham is among several Maine voters interviewed by the Post who had previously crossed party lines to support Collins but now say they will not do so again. Their accounts do not constitute a statewide poll, but they expose a potentially catastrophic weakness in the Republican senator’s reelection strategy.

Collins has long depended on precisely these voters.

In an intensely polarized country, she built a formidable political identity as a Republican who could win support from Democrats, independents and moderates uneasy with the national GOP.

That coalition made her a “political powerhouse.”

In 2026, it may be collapsing.

Collins, 78, is preparing to defend her seat against Democratic candidate Troy Jackson. The contest is already carrying national consequences because Republicans currently control the Senate 53–47.

Thirty-five seats are up for election, including 22 held by Republicans. Democrats need a net gain of four seats to seize the majority.

If Collins loses Maine, the path to Democratic control becomes dramatically easier.

Her problem is not simply that Democratic voters oppose Donald Trump. It is that some voters who repeatedly trusted Collins now believe she failed to provide the resistance her carefully cultivated image promised.

Margaret Shaw, a 74-year-old Democrat, told the Post that Collins’ support for Brett Kavanaugh’s Supreme Court confirmation created “the crack in the teapot.”

Kavanaugh later became part of the conservative majority that overturned the federal constitutional right to abortion, an outcome that intensified scrutiny of senators who had voted to confirm him.

For Shaw, the damage expanded during Trump’s second administration until the entire teapot shattered.

“Can’t she speak out?” Shaw asked. “Can’t she be like John McCain?”

The comparison is brutal because it goes directly to the foundation of Collins’ brand.

McCain became famous for defying his own party at critical moments, most memorably when he cast the decisive vote against a Republican attempt to repeal the Affordable Care Act.

Collins has often expressed concern about Trump’s conduct and Republican policies. Critics, however, have accused her of voicing disappointment before casting votes that allow the administration’s agenda to proceed.

Voters who once interpreted that caution as thoughtfulness may increasingly see it as political theater.

The anger extends beyond Democratic defectors.

Theresa Boisot, a 56-year-old independent, voted for Collins in 2020 and Trump in 2024. She now says she wants both of them gone.

“She’s taking money from other people and she’s not giving it to us poor people,” Boisot told the Post.

“I just don’t like Trump, and I don’t like Susan Collins, and I think they both need to hit the road.”

Her shift is particularly dangerous for Collins.

Boisot is not a committed Democratic partisan who was always destined to vote against a Republican. She previously supported both Collins and Trump, but economic frustration has broken that allegiance.

That suggests the senator could be losing voters from multiple directions: Democrats angry about judicial and Cabinet confirmations, independents worried about affordability, and former Trump supporters exhausted by the administration.

A recent killing has added emotional urgency to the political climate.

Bridgham referred to the death of a 26-year-old Colombian immigrant and described herself as horrified that a young father trying to support his family had been “gunned down in the street.”

The supplied reporting does not provide enough detail to establish Collins’ connection to the killing or explain precisely how it affects the Senate contest. But the reaction shows how broader fears about immigration enforcement, violence and government accountability are shaping voters’ judgment.

Trump recently argued that Americans are angry with congressional Republicans rather than with him.

Maine’s disillusioned voters complicate that claim.

Boisot explicitly rejected both the president and Collins. Others appear angry that Collins did not do enough to restrain Trump when she possessed the power to make consequential choices.

For years, Collins’ political strength came from separating herself from the national Republican brand.

Now she may be receiving blame from both sides: loyalty tests from Trump’s movement and condemnation from moderates who believe she was not independent enough.

Collins still possesses formidable advantages.

She is a longtime incumbent with deep statewide recognition, an established fundraising network and a history of surviving elections national analysts considered competitive. A handful of interviews cannot prove that her broader coalition has disappeared.

But close elections are decided by voters exactly like Bridgham, Shaw and Boisot.

They crossed party lines before.

They trusted Collins before.

And now all three say they will not do it again.

Susan Collins once survived by persuading Maine that she was the Republican who would stand up when it mattered.

Her greatest danger in 2026 is that the voters who believed her are no longer waiting.
