A former U.S. Army combat surgeon with backing from Rep. Alexandria Ocasio-Cortez, streamer Hasan Piker, and an anti-AIPAC super PAC won a New Jersey primary on Tuesday despite last-minute negative attacks.

Adam Hamawy beat a crowded field of Democrats in the state’s 12th Congressional District. The winner of the primary is expected to coast to victory over Republican Gregg Mele in the November general election.

His victory came despite a flurry of right-wing media reports that sought to tarnish the progressive candidate as an Islamic extremist because of his 1995 trial testimony for a religious leader convicted of plotting terror attacks.

Hamawy said he was being targeted with outdated “tropes” as a Muslim in politics. His campaign, which was supercharged by an ad campaign from the independent super PAC American Priorities, demonstrated the growing influence of pro-Palestine donors in contested Democratic primaries.

Hamawy stood out among the 13 candidates in the race vying to replace retiring Democratic Rep. Bonnie Watson Coleman because of his compelling backstory and the large ad spend on his behalf by American Priorities, the super PAC founded to counter AIPAC’s influence in Democratic politics.
