History tells us that Trump doubles down on his lies, even if they’re verifiably false. Perhaps he thinks that the degree of his conviction will serve as a substitute for veracity; i.e., his supporters think, “Someone who insists that much that he’s innocent surely couldn’t be guilty.” History also tells us that Trump suffers exactly zero consequences for his lies, and, indeed, benefits from them. We’re all fucked.
EDIT:
I also don’t think the “mental health” angle is particularly availing, since it partially absolves Trump of responsibility. He knows exactly what he’s doing and we shouldn’t allow him to escape from the consequences based on speculation of dementia or whatever.
