Uh huh. You may claim that but that's not the message I get from his posts. Oh it'd be very easy to make the dems more of a big tent party with nationwide appeal. Have them go federalist/states rights on social issues, moderate on economics(with a focus on effective economics as opposed to small government idealism and fiscal discipline) and favor a humble foreign policy.
If they did that even I'd consider voting for a Dem. There is no chance in hell that the people in power in the land of Dems would ever even think about change the party in that direction.
