No one seems to remember how we got Romney. It is not unlikely that Santorum could have overcame Romney and if Newt had withdrawn from a few States that he had Zero chance of winning and offered Rick his support maybe we could have avoided Zero-2.
Were we talking about ego?
Saint Torum is a religious progressive and would have lost worst than Romney, the establishment progressive. You cannot out-progressive a democrat.
That is why we have Cruz running this time around. He is not a progressive, so he will not need to out-progressive the dems.
