There's an entertaining conspiracy theory that Musk isn't actually pro Dem or Repub; instead he simply realized that everyone who would buy an EV on the left already did, and so now by pandering to the right he can tap into a new market.
But to your point, as the child of someone who parrot's right wing talking points, I am looking forward to see whether their remarks on EV's change over the next few years or not.
Musk switching sides on that seems a good time to re-evaluate who is making the predictions now and why.
