I disagree.
Resume for Edwards: Trial lawyer, brief senator
Resume for Clinton: Wife of prez, short time as senator
Resume for Obama: 2 years as senator
Those are the Dem frontrunners. I think a person who takes a stand on illegals will lock up the swing states in the southwest, and probably Virginia as well.
Clinton has been senator a full term, got re-elected and, let's face it, most people view her as having been the equivalent of a cabinet officer. Obama is not a serious candidate and is only a shield for Clinton during this beauty pageant phase. Edwards will win nothing, Dodd or Biden will do better.
