He's also had plenty of opportunity to retire. In any other field someone his age would have retired long ago. But it's been his choice to run again in every election and keep his iron death grip on the country, knowingly doing as much harm as he personally can to the political process and to the American people. (And yes, fuck the people who keep voting for him, but I also don't think it's quite that simple.)
So yeah, it sucks to wish harm on people in general. But there's a million caveats to that when it's a truly evil person, and when he's had every chance to retire. I mean, isn't that conservatives' whole thing, "personal responsibility"? It's been his choice to keep doing what he's doing until he becomes physically or mentally incapable. After watching Feinstein continue to make decisions that affect the US when she doesn't even know her own name, of course people can't wait to see McConnell gtfo, no matter how it happens.
