Mehlhorn told CNBC that he recently approached the heads of the Mainstream Democrats PAC about the idea of backing a primary effort against the two progressive House lawmakers. "I have been asking them [Mainstream Democrats PAC] if there is any possibility of ousting the most extreme members of Congress, and I have been asking about Cori Bush and Rashida Tlaib," Mehlhorn said on Wednesday. The possible primary fight would be the latest election cycle that the Mainstream Democrats PAC has moved against candidates from within the Democratic Party. The Mainstream Democrats PAC helped defeat some progressive Democrats during the 2022 congressional midterms, according to data from the nonpartisan OpenSecrets. The Democratic Majority for Israel's nonprofit donated $500,000 to the Mainstream Democrats PAC last year, according to an FEC record.
