DAVID: There are two ways to think about a national third party: as a vehicle to get people elected and as a way to change policy. If Elon Musk's plan for the America Party is to elect a president or even compete with Democrats and Republicans for control of the House or the Senate, I wish him luck.

And earlier this month, when Elon Musk capped weeks of mouthing off about the GOP’s One Big Beautiful Bill by announcing the formation of a new America Party, it might have felt like a rare piece of good news for the left.
