Morning Booking Call

Voters head to the polls today in Arizona and Michigan for the GOP presidential primary. Frontrunners Mitt Romney and Rick Santorum are neck and neck in the Wolverine State. Can Santorum pull off a win in Romney's homestate of Michigan? Chris sits down with Rick Santorum for an exclusive interview this Sunday to discuss the race. Let us know what you'd like Chris to ask the former Senator.

Then: Turmoil overseas. As tension escalates between the U.S. and Afghanistan governments, will the U.S. change its strategy in Afghanistan? Also, the discovery of mass killings in Syria following a vote to approve Syrian President Bashar al-Assad will remain in power until 2028. We'll focus on foreign policy as we call on the White House and key leaders on Capitol Hill for reaction.

Plus: Don't miss our power panel: Bill Kristol, Jeff Zeleny, Kimberley Strassel and Juan Williams.

We'll see you on Sunday!
