From CNN:
VERCAMMEN: It's the open convention question. If we wind up with an open convention and someone wants to place your name, throw your name into the hat, would you stop them? Would you be open to that?
PALIN: As I say, anything is possible. And I don't close any doors that perhaps would be open out there. So, no, I wouldn't close that door. And my plan is to be at that convention.
