What’s Really Driving the Left’s Wins In Democratic Primaries?

The article analyzes the recent surge of progressive candidates defeating incumbent Democrats and establishment figures in primary elections, notably in Colorado and New York. It attributes the trend to several factors: increasingly liberal attitudes among Democratic voters, effective get-out-the-vote operations by the Democratic Socialists of America in urban areas, and frustration within the party base over Democratic leadership's losses to Donald Trump. The piece features insights from political science professors Julia Azari and Seth Masket, who break down the relative importance of these factors in driving the leftward shift within the Democratic Party.
