Ehhh, all the Hillary voters would have been pissed and stayed home also. Probably a toss up...
I think the Republican core wanted to replace Trump even though he was killing most of them in the primaries.
You wonder how this could happen? the party just threatens to destroy the candidate unless they drop out and then they bring in the candidate that they want. I was not a Trump supporter during the primary season. To me Trump simply wasn't "politician enough" for the party. Hillary had too much baggage, but the Democrats should have sorted that out before the primaries got rolling. The liberal wing of the party and that is the controlling faction, got their wish with Hillary. But the regular working guy felt otherwise.
