Mitt Romney and His Mormon Faith

Mitt Romney is a front-running Republican candidate for president - and a practicing Mormon. Critics are taking a close look at the Mormon religion and questioning its doctrines. Should a candidate's private beliefs be used as a measure to determine performance in public office? Will Romney's religion be an obstacle as he tries to woo the Christian right?  Also, President Bush nominates Robert Zoellick to replace Paul Wolfowitz at the World Bank and, on Reporter's Notebook, the ethics of interrogation.  The government's own advisers argue that harsh techniques are immoral and unreliable.  Sara Terry guest hosts.
