Sunday on Face the Nation: Paul, McConnell, Lew

Coming up Sunday on Face the Nation: Republicans, religion and the right with GOP presidential candidate Ron Paul (R-TX), Senate Minority Leader Mitch McConnell (R-KY) and White House Chief of Staff Jack Lew.

Congressman Paul seems poised to do well in Maine's caucus - we'll get the results on Saturday night, and Sunday morning we'll talk to the candidate himself. On Tuesday when he finished well in primaries in Minnesota, Missouri, and Colorado, Paul told supporters, "It must be a lot more fun believing in something than just campaigning for nothing." Does he believe he can start winning caucuses? What's his plan going forward in this unpredictable race? Does he see himself as an alternative to Mitt Romney or something entirely different altogether? How is he going to compete with the surging Rick Santorum?

Speaking of Mitt Romney, Santorum supporter and major donor Foster Friess hit on the shaky status frontrunner Mitt Romney has with conservatives when he joked at the Conservative CPAC conference, "A conservative, a liberal and moderate walk into a bar. The bartender says, "Hi, Mitt." Is Mitt Romney conservative enough to win over conservatives? Will Rick Santorum's momentum continue building, or will this week's wins mean little in the long run - fading fast like Newt Gingrich's South Carolina win seems to have done? We'll ask the Republican Minority Leader in the Senate, Mitch McConnell, R-Ky. these questions and more about the state of his party.

McConnell is also leading the charge against the White House about the policy to require Catholic hospitals, universities, and charities to provide free contraception. About the decision he's said, "This ruling should send a chill up the spine of people of all faiths and even those with no faith at all...If the state is allowed to violate the religious rights of one religion it can violate those of others." What more will he tell us?

President Obama has heard the uproar and is announcing a "clarification" of sorts on the contraception decision. But will it be enough to satisfy religious institutions? Or to quiet Republican outcry? We'll talk to White House Chief of Staff Jack Lew about that "accommodation" and whether the White House and Obama's re-elect team see the uproar as a setback to the campaign. President Barack Obama's reelection campaign made other big news this week, announcing its support for Priorities USA PAC. What's the feeling inside the White House on the reversal?
