yeah because advocating for socialism only makes you center-left
That aside, I kinda agree with you, to a certain extent.
The Republicans aren't fascists, but they are far-right. Democrats aren't conservatives, but most of them are just liberal at most, left-leaning at minimum. There are very little far-left Democrats, from the looks of it.
And no real left party in America? What about the Green Party, the Peace and Freedom Party, or the Socialist Party? Are those not left?
