Sen. Bernie Sanders went on air this week to declare that no one in the Democratic caucus polls worse with their own party's voters than Sen. John Fetterman, a claim backed by a Quinnipiac University survey showing 69% of Pennsylvania Democrats disapprove of Fetterman's performance.
Sanders made the remarks Wednesday on Zeteo founder Mehdi Hasan's show, escalating a public feud between the Vermont independent and the Pennsylvania Democrat that has played out across cable news, podcasts, and social media for weeks. The appearance came after Fetterman used a Fox News hit to dismiss Sanders as a small-state senator who has "never won an actual competitive election" and accused him of "helping install volatile and dangerous kinds of candidates."
The back-and-forth lays bare a fracture inside the Democratic coalition that neither side seems interested in papering over. Fetterman has drifted toward right-leaning media and bipartisan positioning. Sanders and his progressive allies have responded by questioning whether Fetterman belongs in the party at all. The polling suggests Pennsylvania Democrats are asking the same question.
On Hasan's show, Sanders did not hold back about why Fetterman keeps turning up on conservative airwaves. HuffPost reported Sanders' blunt assessment of Fetterman's media strategy:
"Look, you wanna get on television, you go on Fox TV and you say something bad about Bernie Sanders, get you some coverage. That's the way it is."
Sanders then turned to the numbers. He told Hasan he is confident Fetterman's standing inside the Democratic caucus is worse than any of his colleagues'.
"It's kind of a sad state of affairs, but I will tell you that I know in Pennsylvania, I don't think there's anybody in the Democratic caucus who has a lower rating among Democrats than John does."
A Quinnipiac University poll supports that assessment. The survey found that 69% of Democratic voters in Pennsylvania disapprove of Fetterman's Senate performance. His overall approval among all Pennsylvania voters sits at 48%. But the partisan split tells the real story: 77% of Republican voters approve of the job he is doing.
That inversion, a Democrat whose strongest support comes from the opposing party, is the kind of number that makes primary challengers start making phone calls. And 52% of respondents said they would rather see Fetterman leave the Democratic Party entirely.
The Sanders appearance did not come unprovoked. Fetterman spent recent days on a media circuit that included Fox News, Katie Miller's podcast, and Sean Hannity's show, platforms where he has increasingly aimed fire at the progressive wing of his own party.
On Fox News last week, Fetterman dismissed Sanders' influence outright:
"I just like to remind everybody watching right now, Bernie Sanders will never represent any more than 640,000 people in Vermont. That's all he's ever done, and he ever will do. He's lost his, He's never won an actual competitive election."
Fetterman went further, casting Sanders as a liability for the party's electoral prospects:
"Stop giving me lectures on how to win. Bernie's not flipping seats. He is helping install volatile and dangerous kinds of candidates and put Democratic seats at risk."
That line referred at least in part to Graham Platner, a Senate candidate in Maine whom Sanders initially endorsed. Platner's campaign ran into a series of controversies, and he ultimately suspended it after facing accusations of sexual assault. Sanders encouraged Platner to drop out after those accusations surfaced. Fetterman, however, seized on the episode, calling Sanders a "carnival barker for an accused rapist."
When Hasan mentioned on his show that Fetterman had been attacking Sanders publicly, Sanders responded with a dry acknowledgment: "So, I wasn't the only one, right?!"
Hasan, who endorsed Fetterman during his Senate primary and once viewed him as a progressive champion, offered his own mea culpa on air. He reminded viewers that Sanders had endorsed Fetterman years earlier when Fetterman ran for lieutenant governor.
But Hasan made clear those days are over. He told Sanders that Fetterman has become "not just awful on multiple issues, especially Israel, but he's openly attacking you all the time and suggesting that you're out of touch with the party, that you endorse the wrong people." Hasan concluded bluntly: "A lot of us got him wrong, I think it's fair to say."
That admission is worth pausing on. Fetterman's 2022 Senate campaign was a progressive cause célèbre. Sanders endorsed him. Left-wing media boosted him. Progressive donors funded him. Now the same voices that built his national profile are the ones trying to tear it down, not because Fetterman changed his positions on every issue, but because he broke with progressive orthodoxy on Israel and started appearing on conservative media.
The progressive movement's frustration with Fetterman has intensified as he has publicly warned about far-left influence inside the Democratic Party. That kind of internal criticism earns applause from the right and fury from the left, and Fetterman appears to have made his choice about which reaction he prefers.
Fetterman has tried to shut down talk of leaving the Democratic Party. He published an op-ed stating he has no plans to defect and that "working across the aisle is the only way forward."
But he left himself a conspicuous exit ramp. In a later statement, Fetterman said he would leave the party only if Democrats "make it official" in the party platform "and say we will never support aid for Israel." That condition is narrow enough to sound like a firm commitment to staying, and broad enough to function as a threat if the party's progressive wing keeps gaining ground on Middle East policy.
Sanders, asked on Hasan's show whether Fetterman might officially defect, did not dismiss the possibility. "That is, I guess, a possibility," he said.
Fetterman's positioning has drawn fire from progressive figures beyond Sanders, with left-wing Democrats increasingly treating him as a party defector in all but name. Meanwhile, Sanders and allies like Rep. Alexandria Ocasio-Cortez have rallied behind progressive primary candidates in other states, reinforcing the ideological battle lines that Fetterman has crossed.
Strip away the insults and the cable-news theatrics, and the Quinnipiac numbers paint a clear picture. A Democratic senator who draws 77% approval from Republicans and 69% disapproval from Democrats is not a maverick. He is a man without a political home, or a man building a new one.
Fetterman has not formally responded to Sanders' Wednesday remarks. Whether he fires back on Fox News, on a podcast, or in another op-ed, the cycle will likely continue. The feud serves both men: Sanders gets to position himself as the authentic progressive voice holding the line, and Fetterman gets to play the independent thinker who refuses to take orders from the party's left flank.
The question is whether Fetterman can sustain a political career built on Republican approval ratings while running under a Democratic ballot line. He insists he is staying, for now. But 52% of the voters in his own state say they would rather he go.
When seven out of ten Democrats in your state disapprove of you and three out of four Republicans cheer you on, the party label starts to look less like an identity and more like a formality.
