I would totally agree with you IF our electorate in any way resembled those of 1972 or 1984.
The fact of the matter is however that it has a far, far higher number of committed Leftists. You’re probably right that it’s not enough to win, but gonna be much, much closer than it ought to be.
If it were the 1970s or 1980s Trump would get a 49-1 or 50-0... But I agree its not the 1970s or 1980s... However this is still a center right nation, and like I said, absolute HIGH water mark for the D’s is 15 states or so plus DC.. the further left whackadoo their candidate is, the lower that number will be... and if they go full on whackadoo they probably won’t get double digits.
