I've heard some arguments saying that if Trump "knew" the election was rigged, he had a moral imperative to do whatever was necessary to maintain the union. The fact that the charges exist at all is proof of conspiracy, and the trial is just a parade. While I don't agree, it's hard to get thru to people that don't agree on the same objective reality.
Sadly this will only be watched as justice porn for the left, the right won't even care.
