Agreed. What Biden has is a population that passionately objects to Trump and the GOP, and thinks he was a close enough match to “Any Competent Adult”. It’s not the same as popularity, so he’ll have to work harder to use it, but at least for a few months he can get some stuff done and count on cheering if he crosses McConnell’s Senate (which, sadly, it looks like it’ll be, unless some Republicans start doing the “maverick” act and occasionally break party discipline.)
If I were Biden, I’d start off by letting kids out of cages, and issuing an executive order cancelling most of Trump’s executive orders, including the Muslim Ban, his Tariff Man ones, and anything immigration related or pollution related, and telling the Spaaaace Forrrrrce that they are now non-military and work for NASA.
He’ll also need a Justice Department in a hurry, which will be interesting if McConnell refuses to have confirmation hearings for his AG and other appointees.
