Fetterman's War With the 'Dirtbag Left'
Fetterman's War With the 'Dirtbag Left'
To understand why Fetterman's Israel comments landed the way they did, it helps to look at the other running feud that has defined his summer: his increasingly public war of words with the Democratic Socialists of America and the broader progressive wing of his own party.
The fight escalated after a wave of DSA-backed candidates won high-profile Democratic primaries in New York, including community activist Darializa Avila Chevalier's defeat of longtime Rep. Adriano Espaillat, chair of the Congressional Hispanic Caucus, and New York State Assembly member Claire Valdez's win over a candidate backed by a retiring House Democrat. Both winners had been endorsed by New York City Mayor Zohran Mamdani, a self-described democratic socialist whose own rise has become a lightning rod for exactly this kind of intra-party argument.
Fetterman didn't hold back. Appearing on Fox News with host Sean Hannity, he described the winning candidates as representative of a "dirtbag left" takeover of what used to be considered safe, traditional Democratic seats. Days later, at the Kennedy Center's Mark Twain Prize ceremony honoring comedian Bill Maher, Fetterman doubled down in an interview, calling it "a really big night for the dirtbag left" and going further than before by suggesting some of the winning candidates held views he considered "anti-America" and "anti-Western civilization." He added that, in his view, many of them weren't Democrats or even socialists in any traditional sense, but rather people he characterized as avowed communists who should "form their own party" rather than continue operating under the Democratic banner.
The phrase "dirtbag left" itself has a specific history. It was coined years earlier by writer Amber A'Lee Frost, a co-host of the leftist podcast Chapo Trap House, originally as a somewhat self-deprecating description of an irreverent, vulgar, unapologetically confrontational strain of online socialist commentary. Fetterman's use of the term to describe elected officials and candidates — rather than podcast hosts — represents an escalation of the label into mainstream political combat, and it has not gone over well with the party's progressive flank.
Brad Lander, another Mamdani-endorsed candidate who won a separate primary for a New York congressional seat, pushed back directly, telling Fetterman that the purpose of primaries is precisely to let voters decide "what kind of candidates we want to put on the field," and suggesting that a diverse array of winners simply reflects a diverse array of districts. Lander went further, urging Fetterman to stop attacking fellow Democrats and either recommit to the party or leave it — a striking rebuke from a fellow elected Democrat, delivered in nearly the same terms Fetterman himself has used against the party's left flank.

The friction hasn't stayed confined to primary politics. Fetterman was the lone Democrat to vote against a war powers resolution aimed at curbing potential conflict with Iran, a vote that passed 50-48 with support from four Republicans — meaning Fetterman's opposition put him not just against his own party's mainstream position, but arguably to the right of some Senate Republicans on questions of military authorization. Critics on the left have cited that vote, alongside his positions on Israel and the government funding fight, as evidence that his break with the party's progressive wing extends well beyond rhetoric into substantive policy territory.
Fetterman, for his part, has framed all of this as a matter of principle rather than positioning. In his Washington Post op-ed earlier this year, he argued the party had catered "to the fringe and agitated parts of our base" on issues ranging from Israel to border security, and suggested that reclaiming a more traditional, blue-collar-friendly Democratic identity — one built around labor, healthcare, and pragmatic governance — mattered more to him than satisfying the loudest voices in his own coalition.
