Purists are determine to elect Hilary
In my state, the purists opposed Rick Santorum because he endorsed Arlen Specter instead of a "pure" conservative in the PA. primary. Now, we have Casey in the Senate and Santorum is history.
Duncan Hunter and Sam Brownback can't win. They're unknown back benchers with no chance against Hillary. Vote for one of them in the primaries and Hillary is the next president.
