In a very narrow way, I get the instinct to treat Musk as a temporary ally, but that is faulty logic. Musk is not just rich, he is the face of the oligarchy we are supposed to be fighting. He built his empire on public money and worker exploitation, attacks unions and public transit, and now uses his platform to boost white nationalists and undermine democracy.
He does not want to take down the Big Beautiful Bill for the same reasons we do. He wants fewer limits on his power.
Aligning with Musk, even tactically, muddies the message. If Democrats want to build a winning coalition, they have to be the anti-oligarch party. You cannot take on corporate power while cozying up to one of its worst offenders. Musk is the system Dems need to be fighting.
