We've talked a lot about Trump's daunting electoral math.
Apparently strategists on both sides agree that there is basically one "Trump victory" scenario: he has to win all three of Ohio, Pennsylvania, and Florida, and has to keep North Carolina red.

I agree with this analysis, but with the proviso that if Trump wins the national electoral vote by anything like a significant margin the electoral math won't be a problem as all of those states should drop into his column in that scenario. However, in a tied, or close-to-tied race, he has a far more narrow and difficult path than Clinton does.
