“I think Trump can carry the day with anywhere from 350-375 electoral votes, but nobody is likely to ever win all 50 states.”
I agree...many states Trump (along with all other Republicans) can never win. But the Midwest will come into play with Trump, meaning MN,WI,MI, with Ohio being cakewalk. PA and possibly IL could be competitive (and costly for Dems) to hold. Lots of other written-off states will be won by Trump, or at least require Dem resources to hold.
Add them up, and I get about what you estimated. If things break for Trump, he could win 400, if not a great night only 300-320 - still good enough.
Yes, we need to have clarity. A clean sweet just isn’t going to happen.
Frankly, I will settle for 281 electoral votes. :-)
