Pennsylvania's Democratic senator says he would "absolutely never move against" his Republican counterpart Dave McCormick, a vow that caps months of bipartisan cooperation and deepening Democratic alarm over Fetterman's independent streak.
Sen. John Fetterman told the Washington Examiner he would not campaign against Sen. Dave McCormick if the Republican seeks a second term in 2030. Fetterman called McCormick "my friend" and "a great guy," language that would have been unthinkable two years ago when Fetterman was raising money for Democrat Bob Casey and branding McCormick a "Connecticut carpetbagger."
The pledge lands at a moment when Fetterman's standing inside his own party has collapsed. Polling reported by the New York Post shows 69 percent of Pennsylvania Democrats disapprove of Fetterman's job performance, with only 19 percent approving. Among Republicans, the numbers flip: 77 percent approve, and just 12 percent disapprove. A Democrat more popular with the other party's voters than his own is not a senator drifting, he is a senator who has already moved.
The reversal is stark. During the 2024 Senate race, Fetterman actively campaigned for Casey and raised money against McCormick. He dismissed McCormick as a transplant with no roots in the state. McCormick won anyway.
Shortly after McCormick took office, the two senators and their wives, Gisele Fetterman and Dina McCormick, sat down for dinner together in Pittsburgh. Fetterman described it as a "great discussion." What followed was a working relationship that went well beyond courtesy.
The senators have co-sponsored legislation together. In July, they filed a joint political action committee called Common Ground PA, a fundraising vehicle that accepts donations from supporters of both men. A spokesperson for the PAC told The Center Square that the donors "value the collaboration exhibited by Senators McCormick and Fetterman for Pennsylvania and want to support both of them."
That structure lets Republican donors contribute to Fetterman's political operation, a detail that has not gone unnoticed by Democratic leaders already watching Fetterman field open courtship from the GOP.
McCormick, appearing Sunday on "The Cats Roundtable" with host John Catsimatidis, offered his own assessment of why the friendship works. The Hill reported McCormick's remarks praising Fetterman's willingness to break with progressive orthodoxy.
"He's willing to stand up and call out the craziness that's happening in his party."
McCormick added that Fetterman's independence has carried a cost within Democratic ranks.
"It's made him unpopular with some of the people in his party."
McCormick said he was "lucky to have a good partner in Pennsylvania" and acknowledged that people have tried to stop him from praising the relationship publicly. He did not name who pressured him.
Pennsylvania is one of only three states with split Senate representation, one Democrat and one Republican, and McCormick framed the partnership as a model for the kind of bipartisan work voters want. Progressive candidates winning Democratic primaries during the 2026 midterms, McCormick suggested, only widened the gap between Fetterman and the leftward pull of his party.
Fetterman has repeatedly said he will not switch parties. At the Hill Nation Summit, he told the audience he had "no plans" to leave the Democrats. On NBC's Meet the Press NOW, he was blunt: "I'm not going to be a Republican."
But he also set a condition that sounded less like loyalty than a warning. Fetterman said he would walk if the party made a decisive turn against 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 is not hypothetical posturing. Fetterman has publicly questioned whether the Democratic Party still has room for pro-Israel voices like his. And his votes have matched his words, including a deciding vote to preserve presidential authority on Iran that put him squarely alongside the Republican majority.
Senate Majority Leader John Thune said in late July that Republicans would "welcome" Fetterman if he ever decides to leave the Democratic Party. Senate Democratic leaders have pleaded with Fetterman to stay, a sign of how seriously they take the possibility.
Fetterman's framing is careful. He told the Washington Examiner he is not changing parties: "It's just, we are Team Pennsylvania, and we work together." He cast the McCormick relationship as state-level pragmatism, not ideological realignment.
The numbers tell a different story. A senator who draws 77 percent approval from the opposing party and 69 percent disapproval from his own is not simply "working across the aisle." He is governing from a position that his party's base has rejected.
Fetterman has publicly criticized the Democratic Party's leftward lurch after progressive and socialist-aligned candidates swept primaries in 2026. He has spent time in the Republican Senate cloakroom. He has formed a joint PAC with a Republican. And now he has promised, on the record, never to campaign against that Republican.
Whether Fetterman ever formally switches parties matters less than what his trajectory reveals about the one he is in. When your most visible moderate is raising money with the other side, dining with the other side, voting with the other side, and now pledging to protect the other side's incumbents, the problem is not the moderate.
