I’m generally a take the high road, forgive and forget, let my neighbor off the hook for cutting down my tree kinda guy, but I would not support pardoning Trump. As others have stated, it’s unclear for what crimes he’d need pardoning, and I believe he’ll be in a lot more hot water than a blanket pardon for federal crimes will cover. Moreover, I don’t imagine much healing is possible for diehard Trump supporters, who will continue to embrace conspiratorial fantasies about the election results and other deep state nonsense for the foreseeable future. Lastly, I think Trump will be much less of a threat to this country moving forward if held accountable for his wrongdoings - preferably in prison, where his ability to fan the flames will be limited.
But Biden and Congress should focus on more pressing issues, and minimize any resources dedicated to investigating Trump regardless. Let individuals, NY and maybe the IRS take a crack at him first.
