The PR stunt with pro-AI regulation was just to look good and allow him some time to setup his XAi company, nothing more.
As for endorsement, Trump / Vance are pretty much as anti-EV as it gets. Doesn't seem to bother Elon neither.
This tidbit pretty much reads like Elon himself wrote it in a pitch for xAI, so I'd say Elon would 100% on board here.
