I like what
this guy had to say back in 2016- (Twitter)
Though I do think "destroyed" is a little strong. I'm hoping the GOP will at least take from this loss the lesson that they don't need to fear Trump, and that sucking up to him isn't any guarantee that it will pay the dividends they hope for. Now if they can just get over this idea that the only way they can lose an election is, by definition, for the other side to have stolen it, they can still have a future as a viable party in a republic run on the principle of democracy.
(Though I could never vote for them, since I just don't agree with their basic principles,
I also could never be comfortable with the idea of a one-party state, even when the one party would be the one I do mostly agree with)
