I don't know how you can come to the conclusion that the senate is all fine and dandy just because the republicans seem to have won it but, the presidential election is apparently false just because you lost it. Proof?
I think Biden will be known as a senile idiot who beat a well-meaning but ignorant incumbent.
That doesn't speak well of either of them, but neither deserves any better.
No that would be Trump. He lost by 3 million. As such, the Electoral College betrayed the will of the people. In Democracies the person gets the most votes wins. So since he didn't and throw in all the Russian stuff, he's illegitimate.
The History Books will write that Donald Trump is the only POTUS to lose the popular vote twice by millions. 3 million to Hillary and 5 million to Joe. This defines Trump as illegitimate. History may remove him from the President's list once his conversation will Putin are declassified.
