Says who? TRUMP? Pseudologia fallacy.
Any loser could say “I was robbed!” and find people like geriatric Giuliani, the Kraken lady and the MyPillow nut to say “Yes he was!” They just can’t find any evidence worth a damn.
There have been many fine presidents. Whether that includes Trump is a matter of opinion, and opinion has been taken according to the Constitution: he lost.
None of those fine presidents, or any president, would have considered doing what Trump is doing. He is The One Who Can Never Lose.
It’s all about his monstrous ego, that’s all it has ever been about. And some people want to see this creature back in the White House.
