Why the GOP Won’t Renounce Trump

Krugman in an aptly titled piece:

All that has happened this year is a move of those white nationalists from part of the supporting cast to a starring role. So when Republicans who went along with the earlier strategy draw the line at Mr. Trump, they’re not really taking a stand on principle; they’re just complaining about the price. And the party’s top leadership isn’t even willing to do that.
