Democrat Senators Kyrsten Sinema (D-Ariz.) and Joe Manchin (D-W.Va.) are being targeted in 2024 for primary challenges through a PAC set up by former AOC staffers. Saikat Chakrabarti and Corbin Trent run the No-Excuses PAC. Both were involved in the founding of Brand New Congress and the Justice Democrats, which seek to recruit and elect progressive radicals to Congress. Their poster child, Alexandra Ocasio-Cortez, is their model Congress member, and both men served on her staff in Washington, D.C.
In the 2018 cycle, these two organizations teamed up to primary sitting Congress members with more progressive candidates. They also picked up a few existing members who had been elected previously. They were successful in surprising incumbents in deep blue districts who did not take them seriously. As Speaker Nancy Pelosi noted at the time, in the districts where these candidates ran, a glass of water with a “D” on it could win. They are not the candidates who earned Democrats the House majority. In fact, credit is given to their radical rhetoric for Democrat losses in the House in the 2020 cycle.
In 2020, two candidates, Cori Bush (D-Mo.) and Marie Newman (D-Ill.), achieved the same Democrat-for-Democrat exchange in deep blue districts during the 2018 cycle. There were no net gains for the party, and outside of these areas, both their primary and general election candidates were defeated. Some were shellacked. Neither group has ever placed a senator nor won an election against a Republican in a red or purple district.
