I personally think he and Tesla can weather this current decline in sales and make it to a world where most people have an electric car. At that point, most MAGA types around the world might just choose a Tesla over cheaper better alternatives for the status, same way many American men buy pavement princess pickup trucks over cheaper, higher utility alternatives.
IF the Maga types would be buying electric cars it'd probably be a Dodge with horns or something alike. Sleek/futuristic was never their thing to begin with.
I'm 90% sure China will be ready, able, and willing to sell a reasonably priced alternative to Americans by the time of the next US presidential election.
And the remaining 10% includes not just that they can't industrial-espionage their way to copying both product and launch vehicle, but also all the combined odds of "WW3" and "the US no longer exists" and the other less dramatic things that may stand in the way.
The most vehement Trump supporters are not the type of demographic that will make enough purchases of Teslas and Starlink to make any difference overall to the company...
He did become the world's richest man and he bought himself and election so I wouldn't under estimate him.
