Seems thus far Trump is backing him. Which means dumping on the MAGA maniacs like Laura Loomer. But that's easy as Musk has just removed her blue tick, along with a few other critical republicans.
The thing is, Musk isn't wrong to a certain extent. US and UK culture are very dismissive of engineering and science in education. The problem is a lot of that is due to platforms like Twitter and the like which allow mediocrity to be monetised while slogging your guts out for a STEM degree just ends in penury.
It's interesting that Trump - while he may have told some whoppers about the effects - has been quite candid about his plans. He will slash government spending. He will expel illegal immigrants. If people voted for him not believing or understanding that, and are now shitting their pants, then it's on them in a way.
This contrasts with Brexit where the whole Leave campaign was a lie.
