I disagree. Most of the folks I know that voted for McCain know nothing of his record. They just believe he is a conservative because of his military record. McCain cannot win without us. He might win with us. If he wants to win the general election, if we hold our ground, he has to come to our positions at least on most of the major issues before most will help. I will require a lie detector test! :D)
To my mind, a major question one must ask oneself about any candidate being considered is "Might this person, if elected, turn out to be a Democrat mole." For Fred Thompson and Mitt Romney, I would say 'no', since they've both demonstrated that they can't stand significant aspects of what the Democrats stand for. But what reason is there to believe McCain couldn't be a Democrat mole?
