Do they deliver? Did Biden "cancel all student debt for an entire generation" like he said he would? Did the Dems stop sending weapons to back a genocide? Did they get Medicare for All? Did they make housing affordable? Did they stop our overseas torture programs? Did they stop drone-striking children?
Because I don't remember them delivering any of that.
I don't wonder why progress is slow, as it is pretty clear: The Republicans are regressive, and the Democrats mostly impede progress.
