I would be stunned if they nominated her again. That would make the Democrats even dumber that I have regarded them. And that was bordering on brain-dead.
Whether she is nominated depends on how much power the Clintons still have. Not as much as they used to, I would guess.
That moment when you realize the rest of the Democratic Party is so weak that not a single prospective candidate is anywhere close to being strong enough to beat Hillary Clinton in 2020.
