Progressive organizations were forced to play defense in the 2024 primaries
Over the last six years, a wave of upstart progressives slowly chipped away at the old guard of the Democratic Party, toppling establishment-aligned incumbents and pushing the party as a whole further to the left. These skirmishes have been one of the defining stories of Democratic primaries since 2018. But newly energized challenges from pro-Israel groups like the American Israel Public Affairs Committee transformed much of the intraparty divide this year, forcing major progressive organizations to rethink their approach to primary season.
Each cycle since 2018, 538 has tracked congressional and gubernatorial candidates backed by progressive groups and leaders. This year marked a dramatic change in the progressive movement's strategy, as the threat of outside spending against progressive incumbents was so strong that it sucked progressive organizations' resources away from backing challengers to incumbents or in open races.
Even more so than in 2022, progressives faced well-funded opposition, particularly from pro-Israel groups like AIPAC and Democratic Majority for Israel — which also spent huge sums to help defeat incumbent "Squad" members Jamaal Bowman and Cori Bush, the only two incumbent Democrats in Congress who lost in the 2024 primary cycle. As a result, many of these groups barely endorsed at all in open primaries.
But overall, more than half of the progressive candidates in open races that we tracked this cycle still won their primaries, similar to 2022. Most of their victories came in uncontested or less competitive races. While these races may not have generated as much attention as the blockbuster Squad battles, each one is worth the same prize: a seat in Congress.
Notably, none of those progressive wins came at the expense of candidates backed by the party establishment. Open-seat clashes between progressives and DCCC-backed picks caused lots of drama in 2018 and 2020, but were effectively nonexistent in 2024. The two wings of the party even endorsed the same candidate in three swing districts currently held by Republicans (New Jersey's 7th, New York's 17th and New York's 19th Districts), signaling a unified front when it comes to targeting key pickup opportunities.
Tonight, we'll be watching to see if the progressive candidates who did make it through their primaries can also win in a general election, particularly those that have the backing of the party establishment, too.
