Brokered smokered, Santorum would easily win outright if Gingrich left the race. I think he will win anyway.
Gingrich has shown he can take a punch and get up from the mat Rick has not won a single big state in-spite of having a free pass by Romney.
I think letting the country vote makes a hell of a lot more sense than either one dropping out. Remember if Romney cant win the majority of the delegates needed by the convention he loses and who ever emerges from the convention will be far more conservative than Romney
