Quick Summary

The article discusses significant turnover in the U.S. House of Representatives during primary elections, with 74 members stepping down, marking the highest since 1992. Democratic socialists within the Democratic Socialists of America (DSA) made notable gains by defeating incumbent Democrats in several primaries, including high-profile figures like Adriano Espaillat and Dan Goldman. However, the article also notes that centrist candidates are crucial for determining control of the House, as most competitive races lean toward nominees backed by moderate PACs like the New Democrat Coalition and Blue Dogs.

Story summary

In the recent US primary season, significant changes took place in Congress. 74 members left the House of Representatives this cycle, the highest number since 1992 according to Pew Research Center data. Among those who ran for re-election but lost their primaries were seven Democrats and two Republicans. Notably, four Democratic incumbents lost to leftist candidates tied to the Democratic Socialists of America (DSA). Additionally, scandal-plagued congressman Cory Mills was defeated after facing endorsements from other Florida Republicans and opposition spending by a Super PAC backed by the renewable energy industry. Another incident involved Andy Ogles, a Tennessee congressman known for homophobic and Islamophobic statements, who lost after being endorsed against by the state's Republican governor. These outcomes suggest potential shifts within the Democratic party towards more progressive candidates in upcoming elections.
