I've contended all along that the majority of Trump's supporters would have been more enamored with him had just said, "ya, I did that porn star...". He'd be an even bigger hero to them. "He's the man banging porn stars, how cool is that!". He's their champion...
And somehow he deluded himself that lying about it was going to work... All it did was make a bigger fool of him in full public view.
