Seeing Pence arrested would be the equivalent of giving up one's queen in sacrifice (re: chess) in order to get your opponent's king, though.
If there is a big first arrest that changes people's minds about everything, I don't see it being on the Left. I see it being on the Right (or RINO), or some neutral/bipartisan individual. Otherwise, it would tear things apart, rather than uniting people. Particularly with the existing media slant to the Left.
