Why does any of this matter, Tom?
As usual you're just trying to derail this thread into minutiae of semantics and definitions.
Biden is acting like he won the election because pretty much everyone agrees he did. It wasn't close, either.
So, of course, he's gearing up to take office.
The only people who think there's some dispute about this are Trump and some of his more deluded supporters.
And tbh, I think even Trump secretly knows he lost, he's probably just doing this to fund raise from his supporters and create the support for whatever he wants to do next.
