Hahahahhaahahhah… there is? Over what exactly?

Basically over who gets to run the party. It's pretty clear that the Biden faction did not want him to go, and then there was a really concentrated push in the media after the debate that set the stage for forcing him out. Even the way he did it was absolutely bizarre where there was no actual reason given, and no televised statement or anything. He's also not resigning as the president so far, which undermines Harris if she's going to be the nominee.

There also seems to be a split on endorsements for Harris with Pelosi and Obama holding out. Yet, it's not even clear whom else they could possible run at this point. I'm personally expecting things to get even more wild going forward.

I don’t see one… you mean the one that wants to destroy Iran, Syria, Venezuela, and China, in foreign policy rhetoric…

Vance directly said that US can't fight every war all the time, so it's a pretty clear sign that they will be picking their battles. Wanting to destroy their adversaries isn't at odds with picking and choosing their battles.
