Politics isn’t rocket science.

If it were, President Donald Trump might have something more to worry about in his reignited feud with his estranged “first buddy” Elon Musk.

But nothing in the explosive and now-soured flirtation of the world’s richest man with politics suggests he has the magic touch to spark the kind of creative disruption in the Republican Party that he set off in the orbital and electric vehicle industries.

Musk’s first-among-equals status as head of the Department of Government Efficiency at the start of Trump’s second administration is now a memory.

He’s so livid over Trump’s debt- and deficit-inflating “big, beautiful bill,” which passed the Senate on Tuesday, that he’s threatening to primary every GOP lawmaker who votes for it and to set up a new political party.
