(the detail is that he’s talking about how she self-identifies rather than her appearance itself, but that would ruin a perfectly good nottheonion moment)
If you watch interviews with him when he was younger, his cognitive decline is shocking. He still comes across as sleazy asshole though.
Even as late as the 2016 RNC debate. He was speaking coherently, responding to opponents, making logical points. He was still lying and promising to do terrible things, but he seemed in control of himself and I could see how some conservatives might call him charismatic even.
Nowadays he just kind of picks a vibe and spews out words vaguely related, and the audience projects what they want him to mean onto it.
