Democrats Joseph Biden (search) and John Edwards (search) are criticizing party chairman Howard Dean (search), saying his rhetorical attacks on Republicans have gone too far.

Dean has said Republicans never made an honest living in their lives and House Majority Leader Tom DeLay ought to go back to Houston where he can serve his jail sentence. DeLay has not been accused of any crime.

Dean "doesn't speak for me with that kind of rhetoric and I don't think he speaks for the majority of Democrats," Biden, the top Democrat on the Senate Foreign Relations Committee, said Sunday on a network morning news show.

While discussing the hardship of working Americans standing in long lines to vote, Dean said Thursday, "Republicans, I guess, can do that because a lot of them have never made an honest living in their lives."

Edwards responded that Dean "is not the spokesman for the party."

Dean is "a voice. I don't agree with it," Edwards, a former senator and the Democrats' vice presidential nominee in 2004, said Saturday at a party fundraising dinner in Nashville, Tenn.

Asked about Dean's remark about Republicans and honest living, GOP chairman Ken Mehlman told one network news show: "I'm not sure the best way to win support in the red states is to insult the folks who live there. I think that a better approach might be to talk about the issues you're for."
