Santorum wins a State that he was projected to win, and that means Romney is done? Youre joking, right? Do you realize the percentage of delegates left that Santorum has to win to win the nomination? If Santorum follows it up with a win in Wisconsin, followed by gaining the majority of the delegates on April 24 (NY, Penn, Del, Conn, RI). Then maybe there is a hint that the tide is turning, but that is highly unlikely.
Romney is done.
A spoiler, who is damaging the GOP.
He should stand down.
