Yes Mitt must lose.
However, how is a vote for Rick a vote for Newt when if Rick wins, he and his supporters, will be right back on their sanctimonious high horse about how such a win is “proof” that he is the true conservative blah blah blah?
What does this have to do with anything?
Do you want Mitt to lose, or are you more concerned about 'sanctimony' than political reality?
I am afraid you are right.
