John Fetterman Is Pulling a Reverse Manchin - Newsweek

When Senator John Fetterman appeared by video at the GOP’s midterm convention in Dallas on Wednesday, a surprise virtual drop-in from the Democrat, he praised Republican Senator Dave McCormick as a friend and ally on Pennsylvania steel.

Fetterman presented himself as a "common sense Democrat" willing to reject socialism and work with President Donald Trump and his Republicans.

Naturally, Fetterman’s appearance among Republicans intensified speculation that he could eventually abandon the Democrats. He later clarified that he was staying in his current party, though perhaps not all of his frustrated fellow Democrats took that as a positive.

The Fetterman cameo at the GOP’s "Trumpalooza" reveals the reason why such a switch of parties could actually diminish the special political role he has built for himself on the Democratic side.

Do you sense a contradiction? That’s the point. Fetterman remains a Democratic senator, with the institutional significance that carries in a closely divided chamber, while an increasing share of his national political identity comes from disputes with Democrats.

For Republicans, that can make his party label an asset rather than an obstacle. For Fetterman, it gives disagreements that might be ordinary inside the GOP considerably more attention and political meaning because of his Democratic colors. Let’s call it the reverse-Manchin model.

Joe Manchin spent most of his Senate career as a Democrat representing West Virginia, even as the state moved sharply toward Republicans. He formally became an independent in 2024 while continuing to caucus with Democrats before leaving the Senate in January 2025.

His leverage largely flowed from Democrats needing a senator capable of surviving in territory where the national party had become deeply unpopular.

Fetterman’s position is different: he won Pennsylvania as a Democrat in 2022 and still occupies a Democratic seat, but some of his most visible moments now come when he departs from his party rather than when he advances its message.

He has supported Israel more aggressively than many congressional Democrats, for example, and backed Trump during the Iran war. He has also helped advance Trump’s nomination of Markwayne Mullin for homeland security secretary and repeatedly criticized the party’s left flank.

At the same time, Fetterman insists that those differences do not make him a Republican. In July, he described himself as potentially the Democrats’ decisive 51st senator if the party regained the majority, while saying he would leave only if Democrats formally became what he called an "anti-Israel party."

The whole figure is politically unusual in a system that has become defined by a strict two-party system (and two-party mentality). Needless to say, Fetterman’s agreement with any Republican cause carries the implied message that a particular position can attract support beyond the GOP coalition, which is an extremely precious political token in today’s modus operandi.

The White House knows that: it promoted the video of Fetterman’s convention appearance on its own social media channels.

A party switch would still offer Republicans obvious institutional benefits: Republicans hold a 53-47 Senate majority, and Democrats would need a net gain of four seats in November to take control under the current alignment. Fetterman changing caucuses could therefore materially alter Senate arithmetic.

Another way of thinking about a potential switch, though, would involve a vote gain alongside the loss of a validator. That possibility was visible Wednesday, as Fetterman’s appearance attracted national attention because a Democratic senator participated in the opposing party’s major campaign gathering weeks before a midterm election. Comparable praise from a Republican senator would have been routine convention business.

Fetterman and McCormick have already pushed their cross-party relationship beyond rhetoric. In July, their campaigns and leadership PACs became participants in Common Ground PA, a joint fundraising committee registered with the Federal Election Commission.

Remaining a Democrat would allow Fetterman to continue that collaboration while preserving the contrast that makes it noteworthy.

Obviously, Democrats are aware of the intricacies of this all, which is why the stronger argument against the arrangement comes from the party.

Fetterman's relationship with Pennsylvania Democrats has deteriorated for reasons extending beyond his ideological breaks with the party. A recent Wall Street Journal investigation, based on interviews with more than a dozen former staffers and lawmakers as well as internal records and text messages, portrayed Fetterman as increasingly disengaged from routine Senate work, including constituent meetings and committee hearings.

CBS News separately obtained some of the messages and reported that a former staffer confirmed the accuracy of the Journal’s account. The allegations have given Pennsylvania Democrats another potential line of attack ahead of 2028: that their disagreement with Fetterman concerns his performance in office as well as his politics. Fetterman rejected the broader portrayal, telling CNN that "disgruntled staffers" were pushing "smears," and defended or disputed the context surrounding several episodes described in the Journal report.

Some Pennsylvania Democrats have moved beyond disagreement: Representative Brendan Boyle called for Fetterman to go after his decisive committee vote advancing Mullin’s nomination in March. But Senate Democrats have offered a different assessment: Vermont Senator Peter Welch defended Fetterman by arguing that Democrats were "quibbling about somebody who speaks his mind and votes with us over 90 percent of the time."

Independent voting analysis points to the same basic paradox: Congressional Quarterly found that Fetterman broke with Democrats on nearly 20 percent of party-line Senate votes in 2025, the highest rate among Senate Democrats, meaning he still sided with his party on roughly four out of five such votes.

His defections stand out because they are relatively unusual and because they tend to come on politically salient questions. That helps explain his peculiar value to both parties: Democrats still receive most of his votes, while Republicans receive something rarer when he crosses the aisle, a Democratic senator validating their position.

So there’s a limit to the reverse-Manchin model.

A politician can derive influence from fighting his own party only while membership in that party remains sustainable. If Democratic primary voters eventually reject Fetterman, maintaining the label could cease to be an advantage and become an obstacle to reelection.

Believe it or not, given how "fresh" Fetterman feels, there are precedents for politicians occupying this awkward middle ground. A primary example: Joe Lieberman lost Connecticut’s 2006 Democratic Senate primary, won reelection as an independent and continued to organize with Democrats even after endorsing Republican John McCain for president in 2008.

Fetterman has not reached that point as he remains a Democrat and has stated plans to stay one.

So, perhaps, the next significant development doesn’t have much to do with Republicans inviting him into their fold but more to do with Democrats allowing him to stay in theirs.

A theory: if Fetterman keeps voting with Democrats often enough to remain institutionally useful while producing his biggest political moments through disagreement with them, the strange equilibrium could endure. If either half breaks—if his voting record moves decisively toward Republicans, for example, or if Democratic voters decide his membership has become untenable—the arrangement becomes much harder to sustain.

For now, Fetterman’s political distinctiveness comes from standing with Republicans while continuing to say that he is not one of them.
