“You forgot Duncan Hunter, Sr., Senator Jim Demint, Alan Keyes, and Michelle Bachmann.”

Representative Pete Sessions, Senator Jim Inhofe, Senator Tom Coburn, and Senator Jeff Sessions are also possible ‘12 GOP Presidential candidates. Nothing is definite yet, and politics is very unpredictable. There could also be one or more people unknown to everybody right now that could end up as top contenders for ‘12 GOP POTUS. Anything is possible in politics.
