You don’t have to be dumb. You can also be evil. All Trump voters exist on a spectrum between dumb and evil to me. I have known a few and they all fall onto the dumb/ignorant side of the spectrum. A lot of them are single-issue voters too.

But honestly, a lot of Republicans are this way. They think their party fights for the working class, despite clear and abundant evidence to the contrary. When a voting bloc like that exists, it’s really not that surprising they can be convinced to vote for someone like Trump.
