Regarding the leaked Romney campaign plan James mentioned below, I found this part interesting:

In other words, Giuliani is the post-9/11 candidate, but Romney wants to be the post-post-9/11 candidate. He wants to lead us beyond to the period of time during which the focal point of political life is our reaction to 9/11. Interesting, but I don’t think Republicans are quite ready to go there yet. Also, given that he wants to run as the “energetic, optimistic, and innovative chief executive,” I wonder if he miscalculated by going too far to position himself as a social conservative. His positions on social issues could have still evolved, but in a more subtle way, and he didn’t have to lead with them or draw so much attention to his new found beliefs. Instead, he may have been better off pitching himself first as a charismatic, problem-solving CEO type, and then only secondarly as a newly-minted social conservative.
