Elon Musk’s brain is grinding gears at high rev, doing no one any favors.

Since stepping away from his DOGE work, he’s been in and out of public hysteria, even devolving into a full-on meltdown.

His latest eruption centers on launching a third party — an idea that last worked in 1858 and only because an existing second party was in total collapse.

Raging over final passage of the One Big, Beautiful Bill Act, Musk says he wants his America Party to hyper-focus on fiscal responsibility, whining: “When it comes to bankrupting our country with waste & graft, we live in a one-party system.”

Yes, the national debt is a big, ugly can that can’t be kicked down the road forever — and both parties are at fault, as neither seems able to cut much spending.

But, sorry: Whatever they tell the pollsters, the voters simply don’t actually reward fiscal responsibility.

More: Elon, like countless businessmen dabbling in politics before him, wants a quick, drastic fix when any political reform under our system of government usually takes decades of sustained effort — and, at the least, careful work.

This basic misunderstanding is a big reason DOGE’s results were rather underwhelming: It’s not a question of new management upending failed practices.

Governments just don’t run like private companies (even though poorly run companies can come to behave like governments).

Set aside the suspicion that Elon “No pork!” Musk’s biggest private gripe is how OBBBA cut electric-vehicle subsidies: The simple truth is that nearly all of the new law’s supposed deficit-ballooning comes from stopping preprogrammed tax hikes, most of which neither party really wanted to kick in.

Log off of politics, Elon, get some sleep and take a long, cool think off before you ever try again.

For now, you’re far better off focusing on what you do best: Pushing American innovation forward through companies like SpaceX.
