I know you're "sort of" kidding, but there was a great editorial by Charlie Sykes (a conservative) about this a few weeks back. Much of what Trump supporters latch onto is that he drives liberals crazy; they figure he must be doing something right if that's the case.
It's a weird standard, and a pretty low one. Though I know people who voted for Hillary who would have felt the same way, intelligent people should set a higher bar for POTUS.
You expect Southern Man to do what intelligent people do?
