There was one consisted theme throughout the debate which focused on which one of these men hated Hillary Clinton the most. Heck,Chris promised that if he was the presidential candidate that Hillary Clinton would not get within a mile of the White House. Marco said she was a disaster and Ted insisted that he would out do making her a disaster. Jeb wanted to get in a point about his dislike of Hillary who definitely would be a presidential disaster unlike the wonderful record of his brother.
If not for the presence of Hillary Clinton the guys on the stage would have no one they could come together on as to be hated. So, in one sense, Hillary is the most important person in this Republican race for the presidency. Oh well, there is always Bill to discuss and Monica Lewinsky.
