Jill Lawrence writes in USA Today about the differences in purposes between the DNC and RNC chairman. Howard Dean is merely trying to shore up the Demo base, while Ken Mehlman is wooing blacks and Hispanics. Dean is shoring up his base, Mehlman is trying to expand it. One Dem says that "Mehlman is playing in our sandbox." Everyone is eagerly awaiting Howard Deanâ€™s weekend TV appearance with Tim Russert. The question is, will Dean do on a national stage what he does in untelevised meetings around the country where he calls Republicans corrupt, brain dead, mean, and "not nice people"? N.Y. Post wonders if Demos will be up in arms after his Russert appearance.
