Democrats’ June primary test: Can the party stop its radical flank?

Renewed scrutiny of congressional hopefuls Graham Platner and Adam Hamawy highlight the potential for far-left candidates to complicate the party’s midterm ambitions

The latest revelations that Graham Platner, the Democrats’ anti-establishment, far-left standard-bearer in the Maine Senate race, was sending sexually explicit texts to as many as a dozen women while he was married — an issue his wife raised to campaign staff as a potential liability — is another sign that the candidate’s extensive baggage may be too much for the party to handle. (As commentator Haviv Rettig Gur posted on X: “I’m starting to think that SS tattoo might have been a red flag.”)

Meanwhile, a New York Times interview, published over the weekend, with leading New Jersey Democratic congressional candidate Adam Hamawy about his past affiliations with Islamist extremists is going to raise more red flags for Democrats.   

Asked about his travels with Omar Abdel Rahman, known as the “Blind Sheikh,” who was connected to the 1993 World Trade Center bombing, Hamawy downplayed the spiritual leader’s jihadist sermons. “He wasn’t preaching death and destruction all the time,” Hamawy said. “He had certain views that he spoke in certain forums, but that’s not what he did every single day.”

With the calendar now approaching June, it’s yet another reminder that Democrats are on the verge of nominating some truly radical and damaged candidates for congressional office as a critical mass of primaries take place this month.

Many of the races are taking place in safely blue seats, so Democrats haven’t raised that much concern over candidates such as Hamawy, whose terror ties (including volunteer work for what was later revealed as an al-Qaida front group) at the very least, raise questions about suitability for public office.

But others, such as Platner, are running in battleground Senate seats where the stakes couldn’t be higher. In California and Montana, candidates are running in swing districts where the battle for the House majority will be fought. 

If May was the month that tested President Donald Trump’s power over the Republican Party (lesson: he’s still firmly in control of GOP voters), June will be the month that determines whether the Democratic Party is going to abandon its moderate moorings and nominate a roster of radicals.

The stakes couldn’t be higher — especially for Jewish Democrats, who have been among the leading voices alarmed by the rise of these candidates, who, not surprisingly, often hold virulently anti-Israel views and don’t have a problem mainlining antisemitic rhetoric

While Platner’s expected nomination and Hamawy’s potential one are generating the most attention, several under-the-radar races will have a direct bearing on the Democrats’ midterm prospects. 

In California’s congressional races, the pro-Israel advocacy group Democratic Majority for Israel has been involved in two swing-district races where the group fears left-wing candidates could jeopardize the party’s chances of a pickup. In the seat held by Rep. David Valadao (R-CA), the group endorsed Assemblywoman Jasmeet Bains and has been airing ads on her behalf in the Central Valley-based district. 

Bains is facing a Democratic challenge from school board trustee Randy Villegas, who has landed endorsements from many of the leading anti-Israel lawmakers in Congress and who many Democrats fear could cost the Democrats a seat if he’s the nominee against the battle-tested Valadao. 

In the race to succeed retiring Rep. Darrell Issa (R-CA) in a San Diego-area district, the pro-Israel group has endorsed San Diego Councilwoman Marni von Wilpert, who is running against Ammar Campa-Najjar, who is of mixed Palestinian and Mexican American descent and has twice unsuccessfully run for Congress. The district was redrawn to elect a Democrat, but it still remains a competitive battleground. 

In Iowa, Democrats will be choosing whether to nominate the party-favored state Rep. Josh Turek, the more moderate candidate, or go with a true-blue progressive in state Sen. Zach Wahls. The nominee is expected to face Rep. Ashley Hinson (R-IA) in a state that Democrats hope will become competitive, given the rough national environment for Republicans.

And in Montana’s 1st District, in the race to succeed retiring Rep. Ryan Zinke (R-MT), Jewish leaders are alarmed by several candidates in the Democratic primary field over their anti-Israel rhetoric and online antisemitic activity. Army veteran Matt Rains appears to be the most mainstream Democratic candidate of the four in the race, but lags behind in fundraising. 

The district has been solidly Republican since its creation, but in a Democratic wave, it’s competitive enough that it could flip. Given the extreme rhetoric of some of the Democratic candidates, however, that prospect would be less likely. 

Also of note: Los Angeles voters will be determining which two candidates will square off in a runoff for mayor. Assuming embattled Los Angeles Mayor Karen Bass finishes in the top two, her opponent will either be running further to her left (Los Angeles City Councilwoman Nithya Raman) or to her right (reality star Spencer Pratt). The matchup will determine whether the campaign focuses more on catering to progressive voters or moderates disenchanted with the direction of the city.
