It's impossible to say, since we don't know what will happen over the next three years. But I was looking through some old election '12 stuff online today, and Steve Schmidt said something in the immediate aftermath of the 2012 election that was rather striking. He noted that the last time a GOP presidential candidate got the same share of the white male vote as Mitt Romney did, in 1988, that candidate, Bush '41, was able to win over 400 EVs. Romney only netted 206 EVs with that share. Right at this particular moment, changing national demographics don't look great for the Pubs, so I would say that, with the right candidate and favorable political circumstances, it's likely. But we know nothing of what the political landscape will look like in three years.
Yes but also you bring up the bigger reason: Hillary or whoever will get a much higher % of the white vote.
