In every election “left-leaning” neoliberals always try to guilt-trip Marxists into voting for their candidates with the usual schpiel: “Your party doesn’t have enough votes to win. You are just letting conservatives win”. What do you tell these people?
Democrats enable the rightward shift. If we want them to actually get better we shouldn’t guarantee the left’s vote. Otherwise they will only shift rightward to get perceived “moderates” between dems and gop.
