have a harder time establishing credibility with the other side.
I saw people saying that about GWB, and about Obama and lots of people saying it about Trump right from the beginning.
Right or left, if you have already stated you hate someone and regard them as illegitimate, your subsequent opinions about them and attacks on them are suspect and subject to a much higher standard of proof from the neutral or middle ground.
We had Tea Party idiots question Obama's citizenship (and, to be fair, people who don't understand the Constitution saying Trump was illegitimate because he only won the EC ),who the hell on the other side is going to pay any attention to what such people subsequently accuse the President who they regard as illegitimate of?
As much as I dislike Drumpf, it is utterly true that MANY on our side have looked for any possible way to get him out of the presidency since the night of the election results.
