Um, Santorum hasn’t taken the catholic vote yet.
It seems to me that if either Rick or Newt bail out tomorrow, whoever is left will still be defeated by Romney. By the time May 29 comes around, TX will probably be for Romney too, as people like to pick winners. Surely CA in June will be for Romney. Romney is winning many states that he will immediately forfeit to Obama, including both of his home states of MA and MI.
