I'm sorry, but the idea that Trump has an ideology, be it the GOP's ideology or anything else besides "whatever is good for Trump" triggered me. From https://en.wikipedia.org/wiki/Donald_Trump#Political_career :

    Trump registered as a Republican in 1987;[ a member of the Independence Party, the New York state affiliate of the Reform Party, in 1999; a Democrat in 2001; a Republican in 2009; unaffiliated in 2011; and a Republican in 2012.

Ditto Musk. Musk sucking up to Trump is a transactional exchange between two narcissists. The vague understanding between the two is Musk gives money to Trump so he can get elected and change the law in favour of Musk, and Trump takes the money so he get get elected and stay out of jail.

The only puzzling thing is why Musk thinks Trump will honour the deal once he is elected and doesn't need him Musk any more. I guess he figures Musk figures he has a lot of money, and can keep bribing him.

Trump's brilliance is he has seemingly convinced a good chunk of conservative America and perhaps yourself that he has a ideology, it is theirs, and that he will implement it even if it comes at some cost to himself.
