@furgar How much do you want to bet a lot of the comments are "I am not a Republican, but my dad is one and he said he was fed up with Trump being such an embarrassment to our country and the world."
I would bet this because every other stupid post on r/AskReddit has examples of "I am not X but I know someone who is."
Not only that, but I am sure many of them are "fellow Republicans" who are just fishing for fake internet points.
