Pennsylvania's Democratic senator says he will "absolutely never move against" his Republican counterpart, a vow that caps months of bipartisan alliance and leaves his own party watching one of its members drift further from its orbit.
Sen. John Fetterman told the Washington Examiner he would not campaign against Sen. Dave McCormick if the Republican seeks a second term in 2030. The promise is striking on its own. It becomes more so when you consider that Fetterman actively raised money against McCormick during the 2024 Senate race, stumped for Democrat Bob Casey, and publicly called McCormick a "carpetbagger."
Two years later, the two senators share a joint fundraising committee, co-sponsor legislation, and, by both men's accounts, a genuine friendship. Fetterman's rightward drift has made him a man without a political home in his own party, and the McCormick pledge is the latest proof.
The turnaround between Fetterman and McCormick has been fast. Breitbart reported that shortly after McCormick took office, the two senators and their wives sat down for dinner together in Pittsburgh. Fetterman called it a "great discussion." The man he once tried to defeat became someone he now calls "my friend" and "a great guy."
In July, the pair filed a joint fundraising vehicle called Common Ground PA. A spokesperson for the PAC told The Center Square that its donors "value the collaboration exhibited by Senators McCormick and Fetterman for Pennsylvania and want to support both of them." The structure could allow Republican donors to funnel money into Fetterman's political operation, an arrangement that would have been unthinkable during the Casey-McCormick race.
Pennsylvania is one of only three states that currently split their Senate seats between the two parties. Fetterman and McCormick have leaned into that fact rather than fought over it, co-sponsoring bills and appearing publicly together.
McCormick returned the goodwill during a Sunday appearance on "The Cats Roundtable" with host John Catsimatidis. He called Fetterman a senator willing to "stand up and call out the craziness that's happening in his party," and said he was "lucky to have a good partner in Pennsylvania."
McCormick also acknowledged that not everyone on his side of the aisle appreciates the relationship. The Hill reported that McCormick has had people attempt to stop his public praise of Fetterman. He has not stopped.
The Republican senator pointed to progressive candidates winning Democratic primaries during the 2026 midterms as evidence of the pressure Fetterman faces inside his own party. Fetterman's willingness to buck that progressive tide, McCormick said, has "made him unpopular with some of the people in his party."
That unpopularity shows up in the numbers. Fetterman now carries a 69 percent disapproval rating among Pennsylvania Democrats, according to the New York Post. Among Pennsylvania Republicans, his approval sits at 77 percent. For a sitting Democratic senator, those figures are inverted from anything resembling normal.
At the Hill Nation Summit, Fetterman addressed the question that has trailed him for months: whether he plans to leave the Democratic Party. His answer was conditional. He said he had "no plans" to switch but drew an explicit line on one issue.
"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 framing, loyalty to the party contingent on one policy litmus test, underscores just how far Fetterman has moved from the progressive wing that once claimed him. He has openly questioned whether Democrats have room for pro-Israel voices like his own, and his stance has put him at odds with a growing faction of the party's base.
Senate Majority Leader John Thune weighed in during late July, saying Republicans would "welcome" Fetterman if he ever decided to cross over. The courtship from the GOP side has been steady, but Fetterman has so far resisted the final step. On NBC's "Meet the Press NOW," he was blunt: "I'm not going to be a Republican."
He also pushed back on the logic of switching, noting that President Trump has gone after loyal Republicans and even attacked Thune himself. Fetterman's retort, as the Washington Examiner recorded it, was pointed: "Trump just liquidated perfectly great, committed Republicans... And now he's attacking Thune. What's going to happen to, like, a Democrat? It's a pretty strange pitch."
Fetterman has vowed before that he will never leave the Democratic Party, even as the courtship from Republicans intensifies. But each new step, the joint PAC, the refusal to oppose McCormick, the time spent in the GOP cloakroom, narrows the practical distance between Fetterman and the party he says he won't join.
The backdrop to all of this is a Democratic Party moving in the opposite direction from its Pennsylvania senator. Progressive and democratic-socialist candidates posted wins in 2026 Democratic primaries, a trend McCormick cited and Fetterman has publicly criticized. The party's activist base has grown more hostile to members who break with progressive orthodoxy on Israel, immigration, or cooperation with Republicans.
Fetterman spends time in the Republican cloakroom and counts GOP senators like Katie Britt among his close friends. He has explicitly rejected the progressive label he once wore. And Democratic leadership has noticed, Senate Minority Leader Chuck Schumer has reportedly pleaded with Fetterman to stay in the party as moderates lose ground.
Fetterman's response to all of it has been consistent in tone if not entirely in substance. He will not leave. He will not campaign against McCormick. He will keep co-sponsoring bills with Republicans and raising money alongside one. He will call the Democratic Party his own while spending his political capital in ways that benefit the other side.
Whether that arrangement holds through 2030 depends on how far the Democratic Party moves, and how long a senator with a 77 percent Republican approval rating can keep calling himself a Democrat with a straight face.
