Palin
Cain
Bachman
Cristy (if he runs)
Their ideologies are very similar. I wish they would all sit down and talk to each other. Only one will be nominated as the Presidential candidate. They need to understand that as the field narrows to one candidate they must give open and full support to him or her. In the primary process it will be come evident fairly early who will win the nomination. They others must then band together in support of that candidate.
This is too damn important to let ego rule your actions.
