It would seem as though all they are doing is rearranging the deck chairs on the Titanic. But het, they are Dems after all, it's not like they follow logic or anything.....
It may be rearranging of deck chairs, but it would dilute the influence of the northeastern liberal establishment, which southern black democrats and western hispanic democrats see as out-of-touch with mainstream America. That northeastern establishment hasn't produced a winner for the party since JFK in 1960, why give it the biggest say in whom the party nominates?
