@Nonilex most importantly, it looked like Paxton was going to win.
So, as he often does, Trump hitched his wagon to the side that was already going to win so he could claim the win for himself.
#Trump doesn't really care about all of that other stuff. He's spineless and oblivious to anything of substance.
He just wants the superficial chance to proclaim himself a winner again in front of his adoring crowd, and all of that factual stuff is just irrelevant annoyance.
