I don’t want to get into a political debate here, but the DNC can thank itself for Trump since they coronated (with no primary!) a candidate who dropped out before Iowa when she ran in the primaries because she had zero support because no one liked her. They also basically ran on a platform of “if you don’t like our policies, you’re a bad person.” I’d imagine more than enough people to swing the election either way pulled the lever for Trump as an explicit rebuke of the DNC’s disdain for anyone outside their orthodoxy.
Anyway. When a party besides the Trump party remembers that persuading the rest of the public (not insulting them) is necessary to win elections, that’s when we’ll have relief from one-man rule by that jackass.
