That's multiple questions that don't really have much to do with each other, if you actually want answers break it apart a bit for real discussions. As to the first one, which was the topic, I agree, ideally, he should have done it sooner. But incumbent presidents just DO NOT get replaced in primaries. Just not how things are done in our system. Now I obviously personally disagree with all that. We shouldn't even have primaries with party nominations to begin with, let alone leave incumbents unchallenged. But I can only advocate for changing these things while living in the actual system we do have. And that one never challenges incumbent presidents who are seeking re-election, no matter which party it is. Same would've been done by the Rs. So like I have said the whole time, if Joe wants to step down, he can. And he should. But no one was/is going to make him, pre or post primary votes.
