A new poll shows Sen. John Fetterman is more popular among Pennsylvania Republicans than Republican Sen. Dave McCormick, a stunning reversal that has fueled open talk of a party switch.
The New York Times, Philadelphia Inquirer, and Siena University released a joint poll this week showing 73% of registered Republican voters in Pennsylvania hold a favorable view of Fetterman, the first-term Democratic senator who has spent the last two years bashing his own party's left flank, defending Israel, and making regular appearances on Fox News Channel. McCormick, the state's actual Republican senator, drew just 63% favorable from the same voters, ten points behind Fox News Digital reported.
The numbers on the Democratic side tell the sharper story. Just 22% of registered Pennsylvania Democrats now view Fetterman favorably. Two years ago, that figure was 74%. Meanwhile, 63% of Democrats in the state say they view him unfavorably, a collapse that leaves Fetterman politically homeless inside his own party and potentially vulnerable to a primary challenge when his seat comes up in 2028.
Among independents, Fetterman still holds a comfortable edge: 49% favorable to 35% unfavorable. But the trajectory is unmistakable. A senator elected as a progressive populist in 2022 now draws his strongest support from voters who tried to defeat him.
The scale of Fetterman's shift is hard to overstate. In 2024, only 25% of Pennsylvania Republicans viewed him favorably. That number has nearly tripled to 73%, the Washington Examiner noted, calling the data a sign of "dramatic political realignment" around the senator. No other sitting Democrat in recent memory has engineered, or stumbled into, anything comparable.
What drove the shift? Fetterman's willingness to break with his caucus on Israel, his occasional alignment with President Trump, and his open contempt for the progressive wing of the Democratic Party. He has openly questioned whether Democrats have room for pro-Israel voices like himself, and he has railed against fellow Democrats who criticized Israeli leaders during the ongoing conflict with Hamas in Gaza.
At the Hill Nation Summit in Washington, D.C., last month, Fetterman laid down a marker that would have been unremarkable in the Democratic Party of fifteen years ago but now reads like a resignation letter. He told the audience his long-term concern was with his own party's direction on Israel.
"If our party ever becomes, and just makes it official, the anti-Israel party, that's when I would leave because that's been a moral clarity for me."
That line, "moral clarity", is not the language of a man negotiating for a better committee assignment. It is the language of someone who has already decided where his line is and is waiting to see whether his party crosses it.
Senate Majority Leader John Thune made the courtship explicit. In July, Thune told reporters he had personally spoken with Fetterman about the challenges the senator faces inside the Democratic caucus.
"I have had conversations with him in the past, as have many of my colleagues about the challenges he faces in his caucus. And there are many of us who, I think, would welcome the opportunity to have him join the Republican conference, but ultimately that's a decision that's up to him."
That is not a vague overture. The Senate majority leader publicly confirmed that multiple Republican senators have discussed a switch with Fetterman. The door is not just open, it has been held open, with an invitation taped to the frame.
Fetterman, for his part, has said he has no plans to leave the Democratic Party. But he has also called some members of his own caucus supporters of "full-on communism," a description that does not suggest a man at peace with his political home.
Not everyone on the right is ready to hand Fetterman a membership card. Matt Beynon, a veteran Pennsylvania-based Republican consultant, told Fox News Digital that Republican voters appreciate Fetterman's willingness to challenge his party's radical wing, but cautioned that the goodwill has limits.
"I think a lot of Republicans appreciate the fact that Sen. Fetterman is willing to stick his thumb in the radical wing of his party's eye on issues like antisemitism."
But Beynon added a warning that any 2028 campaign would force voters to reckon with Fetterman's actual record.
"When it comes time for the senator's re-election campaign in 2028, those same voters will be reminded that John Fetterman votes with Democrats more than 90% of the time."
That 90%-plus figure is the gap between Fetterman's brand and his voting record. He has built enormous personal favorability among Republicans by saying things they agree with. Whether he can hold that favorability while casting votes they oppose is the question that will define his next campaign, regardless of which party's ballot line he runs on.
His relationship with McCormick, Pennsylvania's Republican senator, adds another layer to the puzzle. Fetterman has vowed he will never campaign against McCormick, a pledge that no other Senate Democrat has made about a Republican colleague. That kind of cross-aisle loyalty earns trust with Republican voters, and deepens suspicion among Democrats.
The broader pattern is difficult for Democrats to dismiss. Fetterman won his Senate race in 2022 as a party hero, the progressive who flipped a Republican seat in a tough midterm year. Three years later, nearly two-thirds of his own party's voters in Pennsylvania view him unfavorably. That did not happen because Fetterman changed his position on health care or the minimum wage. It happened because the Democratic base moved left on Israel, and Fetterman refused to follow.
The intra-party friction has been building for months. Sen. Bernie Sanders publicly called Fetterman "way out of touch," a sign that the party's progressive leaders view him not as a maverick to be tolerated but as a problem to be managed.
Fetterman himself framed the dynamic bluntly at the Hill Nation Summit, saying the Democratic Party is "afraid" of its far-left wing. That fear, in his telling, is what prevents the party from holding a clear, principled position on Israel, and it is what may eventually push him out the door.
"My long-term concern has been with the Democratic Party, as I am a member of that, is that our party is going to back away and turn their back to Israel."
Fox News Digital reached out to Fetterman's office for comment on the poll and the party-switch speculation. His office did not respond.
The silence is telling. A senator who has never been shy about speaking his mind chose not to comment on a poll showing he is more popular with the opposing party's voters than with his own. Either he is weighing his options more carefully than his public statements suggest, or he has already decided and is waiting for the right moment. Either way, the trajectory has been clear for a while.
When a party loses a senator, it is usually because the senator lost an election. Democrats may be on track to lose Fetterman because they made it impossible for him to stay, and that is a failure no poll can fix.
