Impeachment, conviction remove from office but Trump is leaving anyhow. If a trial occurs after Jan 20, it would bar a private citizen from running for office. Forbidden by Constitution: Bill of attainder, legislature usurping job of courts to impose punishment. Could impeach anyone, bar from office.

No that’s not how it works here. We, the citizens, decide whom we want to vote for. The elite don’t decide for us. That’s the Soviet Union, China, or Iran. You want to live under a system like that? Be my guest and move there. But don’t even suggest that I live under such a system.
