The deviant sexual assault folks usually end up being Republicans. (We know one who was convicted recently…)There is no indication of the guy's politics, it appears that you just made it up that he was a Democrat.

Also the ones who commit voter fraud, usually the same.
And we know another who kneels in front of Vlad, so there is that too. Loneliness is powerful motivator. Poor @Rightguide
