AOC and her supporters believe they're winning. They won't take a back seat to anyone, even for the sake of party unity.
Bill Clinton knew how to get elected. He had advisors who focused on a winning campaign. I’ve never paid much attention to Rahm, but I suspect he knows something about how to win an election.
The flip side is Hillary. She can’t campaign. She doesn’t know how to win. She’s not focused on that. She just wants the power. That’s all she thinks about. The Democrat Party is now run by people more like Hillary and less like Bill. They live their lives like rulers and they insist that everyone do their bidding — but most of them forget that you need that winning campaign before you get to rule.
