On the same theme, Carol Costello takes a more personal look at how each man deals with discussing his personal faith in his political life as a presidential candidate.
Senior Political Analyst Bill Schneider goes back to Iowa, where the 2008 presidential campaign began in early January. The state known for its first-in-the-nation caucus is shaping up to be a November battleground.
