Today’s primaries in Kentucky and Pennsylvania may well serve as an early test over which party is more effectively dealing with its own antisemitism problems. 

Rep. Thomas Massie (R-KY), one of the few remaining anti-Israel Republicans in Congress, has been spewing antisemitic tropes in the closing days of the campaign, portraying Congress as Israel-occupied territory and caricaturing wealthy Jewish donors as the fuel behind his opponent’s support, as he tries to fend off a serious challenge from Ed Gallrein, who is endorsed by President Donald Trump.

Meanwhile in Philadelphia, state Rep. Chris Rabb — who shared a post on his Instagram account promoting a conspiracy theory that the Bondi Beach terror attack in Sydney in which 14 Jews were killed was a false-flag operation perpetuating Israeli interests — holds the late momentum in an open Democratic congressional primary to succeed retiring Rep. Dwight Evans (D-PA). (Rabb’s campaign blamed a former campaign staffer for the offending post.)

A parade of progressive stars, from Reps. Alexandria Ocasio-Cortez (D-NY) to Jamie Raskin (D-MD), have traveled to Philadelphia to campaign with the Democratic Socialists of America-backed Rabb. Antisemitic streamer Hasan Piker likewise rallied with Rabb and held a fundraiser with him where attendees chanted: “Free Palestine!”

Sen. Cory Booker (D-NJ), representing the more mainstream wing of the Democratic Party, held a rally on Monday to boost one of Rabb’s leading challengers, state Sen. Sharif Street. 

Gallrein and Rabb both appear to hold late momentum in their respective races. If the two end up winning, the conventional wisdom — and corresponding coverage — will rightly conclude that a Massie defeat came as a result of Trump’s outspoken opposition to the congressman and that a Rabb victory will be the result of progressives’ ascendance within the Democratic Party. 

But that will only tell part of the story. If Republicans end up ousting a lawmaker trafficking in some of the ugliest bigotry, while Democrats anoint a future lawmaker pushing extremist antisemitic conspiracy theories, it’s a sign of the direction both parties are headed. 

It’s well-documented that antisemitism is rising on both the left and the right, especially among younger Americans. As many experts have noted, it takes leaders calling out anti-Jewish hate from within their own party to combat it most effectively. 

To be sure, Trump’s fury towards Massie has little to do with the congressman’s antisemitism. It’s mainly a result of the congressman voting against several of the president’s legislative priorities, while pushing legislation to require the Department of Justice to release files on Jeffrey Epstein. 

But at least he’s giving the party cover to confront its own extremism. The comparative silence over Rabb from Democratic leaders speaks volumes over how hard that is to do.
