Obama was the commensurate smoozer. He's a natural at giving a speech, getting people motivated, that sort of thing. Doer? Nope. He leaves the heavy lifting to others.
Clinton was, and is, a complete slime as a politician. He's sharp and shifty. He'll do whatever to get ahead and can shift directions in an instant. He's also very aware of the political winds and moves with them to his benefit.
Biden has always been an idiot. He's been on the wrong side of virtually every major US policy or foreign policy decision made in the last 50 years. But he has incredible luck at getting elected. Can't fault that.
Kamala is worse. She's a radical Leftist, an idiot, toxic to her staff, and a completely incompetent manager. Once the new car excitement and smell wear off in a few weeks watch her crumble in the polls. At a podium, she comes off as condescending, grating, and clueless. That performance isn't going to suddenly change.
