Add the Sabato 10%. IMHO they know Biden will loose, he is their sacrifical Bob Dole if you will. Their goal is not to give him a mandate aka > 50%, this is why they want the mail in voting, to delute that because they know even in deep blue east and west phuchistan states, (aka CA & even MA) their are people mad as hell and they are not going to take it anymore and vote for Trump just to stick in thier mask.....
With the mail-in voting nonsense and outrageous claims that “Trump won’t leave if he loses” it does seem like they’re setting themselves up to claim that Trump’s win was not legitimate. Seems like a post-defeat fundraising strategy.
