This should be a game changer in favor of getting the GOP to rally behind who will likely be the eventual nominee --- something that has been the writing on the wall pretty much from the get-go. Santorum will likely win Louisiana this weekend, and that will probably be his last major win. Romney has half the delegates he needs for the nomination, twice as many as any other candidate. This race is all but over barring any April surprises.
