I'm fine with Republicans attempting to impeach Biden. It will fire up the extremists on the right, but it will also fire up Democrats while turning off any moderate voters out there. It hurts republicans far more than it hurts Democrats, it makes them look like petulant children, and that should help persuade voters to push them out of power. If they are going to abuse the tools of power, which they will, I would rather have it happen with Biden, who is about as clean and boring as a politician gets, rather than having them going on a fishing expedition and finding something like Clinton.
