If Biden is the nominee, the Debates would be borderline unwatchable. And that is not good for democracy at all. The only debate that could be worth it would be the VP debate. If it is a Pence-Abrams debate, that would be a great thing to watch, or even if its Pence-Jayapal. But a Biden nomination, and then the debates? Can networks underbid to not cover the debate?
That assumes there's even gonna be a debate in the first place. Trump has already floated the idea of not debating at all (because networks are treating him unfairly...).
and of course, VT - and he did just that.
It speaks volumes though, that in 2016, VT gave Sanders 86% and all the delegates. This time, Biden remained viable (20%) and Sanders got only 50% of the vote.
WA and ID should be Bernie's
WA, maybe. WA was a caucus state in 2016 and chose Sanders but in the non-binding primary shortly after it chose Clinton. This time around, it's just a primary. Seattle proper may give Sanders a victory, but the rest of the state may tilt to Biden. The state doesn't have a large Black population to speak of, but it IS an open primary as well and I could see Republicans voting in the Democratic primary as a way to ensure that if the state's EC votes will remain Democrat, they at least go to the least objectionable candidate.
ID...if the story in OK repeats itself (2016 Sanders victory; 2020 Biden victory), I could see Biden winning Idaho as well. ID was also a caucus state in 2016 and has gone to a primary this time around.
MI and MO should be VERY interesting, though
MI will be THE state to watch. Bernie's surprise win in 2016 is still fresh, but the question is whether he replicates it or whether that was anti-Clinton vote (like it was in WV and KY).
MO I think will go for Biden. The STL and KC areas have large Black populations, and given that MO is an open primary state, I could see suburban independent conservatives voting to support Biden if it means getting Trump out. The question there is by how big of a margin.
ND is unknown
Would not be surprised if ND goes for Sanders. Their "firehouse caucus" is strange and unpredictable. HOWEVER, ND is conservative and even though it's a caucus, there could very well be another case of anti-Clinton activism that propelled Sanders to victory in 2016 but may not be there in 2020.
Regardless of who wins, if Sanders does not win convincing majorities (like Biden did with AL and VA), he'll be neck and neck with Biden all the way. TX and CA were supposed to be the kingmakers and give Sanders the lead he needed to be the undisputed frontrunner. Now, it's essentially delegate socialism: the top performing candidate gets a bigger share of the pie, but not a majority.
