As the most recent poll supports, the idea that Joe would fare better as an independent is puzzling. It's premised on the idea that Republicans would sit out a three-way race, given how much they love their Joey-bear. But Republicans would, you know, actually try to win such a race. Joe-the-Independent running against a well-funded Republican wouldn't necessarily fare so well.
Still, Lieberman's running as if going independent is what he thinks is the best strategy. Methinks it's because he thinks the Republicans really love him.
They don't, Joe. Nobody does.
