Maybe. But the GOP “rebels” didn’t really want anything substantial from McCarthy and they don’t threaten capitalism in the slightest. On the other hand, the few left-wing Congressmembers playing hardball would get crucified by the mainstream media and by the Dem primary voters. Remember, when a pollster asks a Dem primary voter about good policy, the Dem primary voter will generally be in favor of it - first because they want to look like a good person to the pollster and because they want the Dem party to look good in “Dem primary voters polls” that get published everywhere in mainstream media. But when it comes down to it, they will vote for the Iraq war-supporting neoliberal candidate. And they will do it multiple times in a row!
