I am not sure which is more dangerous. Trump really believing he won which suggests disconnection from reality OR Trump knowing he didn’t win but carrying on anyway to subvert democracy.
It possible he is both, disconnected from realty and knowing he's a loser, but no narcissist will ever admit it - which suggests some form of schizophrenia.
He has pretty much put democracy in America on the ropes by his constant BIG LIE that our elections are rigged, which fool some of the people all of the time. Of course many of trump supporters on the USMB are opposed to democracy, for what reason and without any substitute does not support rational thinking.
