The earthquake-level threat is rattling Capitol Hill, igniting panic within the GOP, and sending shockwaves through the White House.

This fight is about far more than one bill—it’s about who holds power in the Republican Party, whether billionaires can directly shape candidate selection, and how fragile political alliances have become. Musk’s threat could either stand as a bluff—or mark a tectonic shift in political financing and influence.
