Third parties do exceptionally poorly in the US. It'll make no difference.

It's all, 100% theater and spectacle.

I don't have any interest in contributing to the endless stream of value judgements of Elon Musk's motives, personal virtue, self interests, etc. He's a loon but I knew that even when he was campaigning for Trump. He's no worse than Trump in terms of character.

Tables turned in some weird alternate reality, I could see Trump acting much worse than Musk is acting if he were playing second fiddle.
