It is sad and what is worse is that Santorum knew this would cause a serious rift with his base, but he did it anyway. We warned him, begged him not to do it, but he did it anyway. It's very easy to pontificate about pragmatism, but when a politician does that which he knows and understands will cause a rift with those who've worked tirelessly for his election, then he has no valid reason to complain when we abandon him. He abandoned us first. That is all lost on the majority of posters to this thread.
Your contention seems to be that Santorum would have been better off disrespecting the President and the senior senator from his own state, in order to curry favor with you.
