Jokes on him, because no one in the DSA trusts our candidates to actually hold anything up.
Joking aside, it's an odd and revealing posture for Carville to take, because it seems to give power to his enemies.
If someone like Carville says 'I've got no problem with the left. We're a big tent', that's politician speak for 'they're useless, and I'm not afraid of them having any influence.' But when he says that he'd rather leave the party than share it with Piker, he's basically cucking himself. Despite having far more power in the Democratic party, he's basically saying that some streamer most people have never heard of is the new kingmaker, and he for all his wealth and influence is a helpless has-been.
Which I like. But it's weird for Carville to say it.
