Ted Cruz (Republican senator from Texas) comes up for re-election in 2024. Couple of remarks about Cancun every time the weather gets a bit chilly, update some of the fun memes from the 2016 presidential primary... and maybe Cruz himself is considering another go at the White House.

Or perhaps that was the situation at the beginning of this year, and one of Musk's motivations for moving to Texas, beyond his previously-stated ones.
