Sorry, not buying it, especially these favorable numbers seem completely off.
Biden and Bernie are ahead by double digits in Michigan and Pennsylvania, even tied or ahead in Iowa and Ohio. While the double digit leads seem too high as well, Wisconsin isn't voting that much to the right compared to Pennsylvania and Michigan. It is, however, the state Trump is most likely to win or the one he will perform best among these three.
The only problem with your logic is that neither Biden nor Sanders will win PA and MI by double digits, yeah both of them would be favoured but there is absolutely no way they win these two states by such lopsided margins.
