Musk has effectively executed a hostile takeover of the United States. He will answer to no one and each time his will is challenged, he will threaten to spend millions on opposition to every Republican who does not fold to him. He doesn't have to go through with it because having to combat the endless coffers and social media influence of Musk is nightmare fuel to every House member. Further, with the House so close, most of the time he won't have to move very many members to make it completely untenable. Johnson won't even bring anything forward without Musk's approval.
Since Musk doesn't have to care about voters, he is going to touch every traditional political third rail and laugh about it. It is going to get bumpy quick.
The only real question is what Trump will do about it, if anything. Musk is far smarter than Trump and despite his awkwardness, he is far more charismatic than every other wannabe Trump/MAGA heir. Musk has an aura about him that people worship. When we were debating what smart politician would take over after Trump on the right and be able to pull the same shit...no one saw Musk coming. He's a fucking tool who will go to any length to get what he wants regardless of the consequences. If someone showed credible evidence that Musk messed with voting, I wouldn't even doubt it for a nanosecond.
