By your logic, Obama was lying his ass off too, he promised public option, action on bankers, stop fracking, closing GITMO and yada yada yada - there is a huge list on politifact.
And then we got Trump, so a more progressive nominee leads to a Republican in the next election cycle.
You see, I can use flimsy logic as well. You ignore everything that's done, harp on things that didn't get done (weed legal? what?) and then promote people who have done nothing in their lives for anyone other than themselves. Cornel West is a troll who is addicted to attention like Trump just like the Green Party funded by Russians and Republicans.
