Conservatives don’t like California. Electric cars are a “liberal” thing. Except when a guy like Elon says government bad, California bad, taxes bad, I’m moving to Texas to hang out with the cool kids and then all of a sudden he’s made it acceptable culturally for conservatives to own electric cars because hey he’s a Texas guy now. Pair that with his maverick reputation and now he’s yet again accelerating EV adoption by reducing cultural barriers. It’ll be telling if Texas reverses their anti-market laws preventing Tesla from being able to sell cars in Texas. That’s the first sign.
Elon doesn’t need to win over liberals - they’re on the EV train already. But he does have to make friends with and win over conservatives.
Does he have this master plan? Doubt it. But it’ll work out this way anyway IMO.
