Still too early for me to make a prediction about who will win, I think that it all comes down to who the Dems pick to run in place of Biden and whether the electoral colleges like him or not.
I think Trump will win the popular vote either way, that much I am confident in.
I was talking to my dad earlier and he seems to think that RFK could be a bulwark against Trump getting the popular vote if he was nominated for the Democratic parties candidate, but RFK is already deep in his own platform.
As far as RFK goes, though, I think some of the "anyone but Trump voters" that are not loyal democrats might vote for RFK now instead of Biden.
