The wheels I assure you are already spinning. Guys like Rubio in the GOP, Whitmer for the Dems, they are all already organizing teams, discussing polling results and how to adapt to them, and thinking about fundraising. Rubio has to be the odds on favorite for the GOP. Who else you got?
And for the Dems, Whitmer seems like a promising front runner since she can motivate women to vote and is from the midwest. Hard to see a nominee that reflects the social values get it, given last night. So does not auger well for Newsome. Who you got?
And remember, Trump is a lame duck even before taking office. He will need to get done whatever he wants to get done in the first 3-4 months because after that people will be jockeying for position within his own party to own whatever is going well, and distance themselves from any trouble spots.
