You have almost no far left in the US. You have extreme ID politics (that are distributed on the far right, the right, the "extreme center" and socdems) and a bastardized radical center[0] that include almost every politicians, even those who appear socdems or far-right. And here i'm using far-right to designate people who want to come back on minority rights, and i separate it from the right.
(Because when supposed "far left" organizations use the word "empowerment", i just facepalm, that's "third way" bullshit imho)
I think Musk doesn't really understand his politics, and that's what hurt him. He should be in the extreme center (with Hillary, or Bush), but he was caught in ID politics for a long time.
