The group that worries me isn't any of the ones you enumerated here. It's the know-nothings, the folks who can't trouble themselves to learn anything about politics or government and will vote purely on impressions they've absorbed from social media and word on the street. They may vote red because they've always heard "liberal" was stupid or because Trump upsets some folks they don't like, or because something about the price of eggs. They may be as intelligent--potentially--as you or I or anyone, but they don't care to use that potential. And there are waaaay too many of them for anybody's safety.
