Joe Lieberman is evidently thinking of running as an Independent. I hope he does it and I hope it’s a trend. The way our parties are currently set up the extremes have way too much power.
UPDATE: Of course the Conventional Wisdom (something I loathe with a passion because it is so boring and so stultifying to the mind and the imagination) is that third-party candidates cannot win. But imagine if this guy were running for president as an Independent. Who would beat him? At this moment, the only people who can defeat him are the reactionary ideologues of his own party.
