Not wishful thinking... Maybe precognition, or intuition, something like that.... Ron has now seen for himself that he can win the nomination, and having had that realization, he has decided that he will do it. With our help he will own SC by this time next week.
I think you're definitely right about Ron. After Iowa he seemed really pleased to see another big sign that people are waking up finally to the message of freedom. His confidence and happiness then seemed to be the sort of knowing that the future of liberty is in good hands. After New Hampshire though, I immediately noticed an even more profound shift in his demeanor. He knows he can win.
