Tony Fabrizio writes for RealClearPolitics about the "lesser of two evils" voting segment in 2016, which he argues is (a) large and (b) somewhat conservative in values. These folks don't like either Trump nor Clinton.
Fabrizio argues the trick for both campaigns is to figure out how to get these folks, however reluctantly, to pull the lever for their candidate. Given what you've read here concerning these two, I find this article particularly relevant.
