Rick Santorum of Pennsylvania, the US Senate's third-ranking Republican and author of the new book, "It Takes a Family: Conservatism and the Common Good," was Wednesday's guest. Here are excerpts from his remarks:
"Does it bother me? Absolutely not. Is it useful politically? Probably the same. I was never supposed to win any race because of being a 'polarizing figure.' One of the great gifts I have had is that I have never really worried about winning my next race. I have always worried about doing the right thing."
"I am making no plans. I don't anticipate making any plans, because it is not my intention. The reason I leave this little window open is because I have no idea what's going to happen.... Is there some strange, remote set of circumstances that might change that? Sure. But it would be a strange, remote set of circumstances."
"The case I make is the case I have made for years, which is [that] I am effective down here."
"[Release] would have a chilling effect on getting sound and sincere legal advice. And the benefits are very minimal."
