Senator Rick Santorum: Well, I will be honest with you. I have six children ages 4-14. And the idea of coming off a race of the intensity that I am engaged in at this point and turning around and running another two year campaign for president is not something that I believe is in the best interest of my family, which I say in the book, and I believe in my heart it's my principal responsibility. I can't speak for other politicians but I can speak for me, and my intention is not to run in 2008.
