Captain Ed is all over it:
Hillary can't have Bill on the stage with her because he overshadows her. She can't have him campaigning separately because it gives the impression that she is nothing but a straw man (or woman) for a third Bill Clinton term as President. They had hoped to keep him at home, apparently, but Barack Obama has created a charisma deficit for the front-runner -- and now she has to evoke Bill at her campaign events to make up the difference.More eveidence that the only thing Hillary stands for is Hillary. That woman won't make a choice at a vending machine without consulting polling data.
