I agree that Trump won’t get 70%, but 65% is easily within his reach. Just the numbers from this poll put him at about 61%-62% of the white vote (when normalized to 100%).
At 65% of the overall white vote, he just needs to pluck off a relative handful of Hispanics and blacks to get over the top. Anything more, even Romney’s bad Hispanic/black numbers, means a landslide.
And don’t forget - most of that 65% of the vote is concentrated in very critical states (i.e., PA and Rust Belt). The states with the really high minority counts, CA, TX and NY won’t matter for Trump - they’re already decided (except, maybe, in a landslide win).
I agree that if Trump manages to win 65% of the white vote then he is going to win the Presidency, and it won’t be a stay up late to see who wins affair like it was with Bush in 2004.
I don’t think he’ll win 65%, but I hope I’m wrong. If he wins, I think it’ll be close, with him winning 62-63% of the white vote, holding all of Romney’s states, and flipping a few of Obama’s, resulting in a close electoral college win.
But I’d love to be proven wrong and see Hillary beaten soundly like she so justly deserves.
