Fascinating exchange between two liberals on MSNBC last week. It got a bit heated! Interested to hear some opinions from individuals here regarding the forces in the Democratic party trying to pull it further to the left, vs. those pulling the party to the center. Which will win out, which should win out for the party to succeed short term and long term. Similarly, to those who think it should go more towards the center, is this simply because the ultra left (socialism as O'Donnell puts it) is currently unattainable at the moment in the American political arena?
