Biden should offer Trump a pardon for his part in the failed coup if Trump first publicly admits that there was no fraud in the election. This is not to excuse Trump, but it is to perhaps show some of his supporters they have been lied to. Many won't believe him, but it would go a long way toward convincing the ones who aren't completely crazy yet to embrace reality. The pardon should be specific to that one event, and not include all the other things he is responsible for. Trump might have a chance to get out of his other transgressions, but the coup attempt would put him in prison for a long time, or worse.
Actually it WOULD excuse Rump. That's exactly and literally what it would do,
So NO, absolutely not. Rump's been enabled all his worthless life to shirk every responsibility. THAT SHIT IS OVER.
