His current worldwide sell is buttressed by interventionist public policy to promote EV, and state backed investment in corporate space exploration. The one exception I'll make there is starlink, which appears to me to be designed to bootstrap business which steals the lunch of a lot of ground-technology communications businesses.
Do you honestly think the Republican policy for capital investment and tax necessarily favours his core businesses in Cars and Space? I don't personally think so, short term. Long term, when the current cohort of Republican leaders are dead, who knows? It's not the party of Lincoln right now, and I'm focussed on Musk, and the economy right now: I don't think Republicans like Californian EV market interventions, or the disruption to the telecommunications sector.
But I could be wrong.
