Although Graham Platner’s implosion was a setback for the left, they’ve been flexing their muscles in races from New York City to Colorado. And according to Gallup polling, the share of voters who describe themselves as “moderate” has fallen from 43 percent in 1992 to 33 percent today. Within the Democratic Party, meanwhile, self-described liberals now outnumber moderates almost 2:1.

This puts the center-left in an awkward predicament. Voters might want independence from the major parties. But they don’t necessarily want more moderation; in fact, they are more willing to experiment with more radical approaches…. Excessive partisanship may drive away moderates — but if they exit the primary voter pool, that only makes the remaining voters in the Democratic primary electorate even more progressive and partisan. Outnumbered in the Democratic Party, but having little in common with the MAGA-fied version of the GOP, the center-left is at risk of becoming politically homeless.
