I was hoping Sanders supporters wouldn’t show up. Hopefully even 20% won’t show up. my biggest concern is actually Republican voters who are going to stay home in protest of God-knows-what. Even if its 10% that’s a lot. And George Will can go to hell as well as National Review.
Whatever the fraction is, the attrition is inevitable. Trump is either causing or capitalizing on a shift in the political alignment. Whatever the republicans claimed to stand for, that's lost persuasive value.
