Sorry 'bub but the Democratic party is as much to blame as republicans. Neoliberalism has infected both parties and let us finally shed this fake reality that the democratic party is the party of labor and not corporations.
Good news is that if you want the democratic party to become the party of labor, now is the absolutely best time to have a real impact in your community.
The absence of evidence is not the evidence of absence.
I will tar and feather the "right" constantly. The "left", here, is somewhat better. As you say, though, neoliberalism has infected both parties.
Personally, I'll take the DSA over both. However, the population is unlikely to accept Sam's. And both political parties would sooner collude than accept the DSA as a modern inheritor of American Liberalism.
