I certainly get how a Trump-like figure manages to temporarily (or, eek, permanently) dominate American politics, though I admit I don't precisely get how Trump himself does. Point being, I get how a racist asshole with a little charisma and charm could manage to achieve it, but Trump seems to lack the charisma and charm part. I mean, he has the charm of a typical sports radio caller who calls in on Monday to complain about Sunday's loss.
