Catholic nuns: Taking on Rome and Republicans

A group of Catholic nuns have embarked on a bus journey through America's heartland to protest budget cuts proposed by a Republican legislator which they say will leave millions of the country's poor even more vulnerable. Wisconsin Congressman Paul Ryan, himself a Catholic, says it was his religious principles that inspired his plan, arguing that it will help the poor by making them less reliant on government. So how big a role does the Catholic church play in US politics? Guests: Stephen White, John Gehring, Sister Marie Lucey.
