DNC Chair Howard Dean is pushing the Democratic party to the left through the organization that survived his run for president. He is raising money for more consistently "progressive" candidates like Donna Edwards who is running against Maryland Congressman Al Wynn, who Dean refers to as a "Bush Democrat."
And yes, I know Democracy for America is officially run by Mad Howard's brother Jim. If Jim were really going too far left for Howard, though, DFA would be shut down immediately.
