Finally the dang thing is over.
Personally, I think Trump didn't lose to Biden, he lost to coronavirus and himself. Under a normal election with most of the same factors, Trump would have won easily, but blotching the whole response to coronavirus and the consequences afterwards really hurt him badly.
Still, I don't think the circumstances that got Trump elected have been resolved, and getting complacent could see us another, possibly more competent, Trump in the next election. The real fight is ensuring conditions are such that it won't happen.
