This Sunday on State of the Union...

Interviews with two presidential candidates hoping to disrupt Newt Gingrich and Mitt Romney’s top tier status. First, we talk to Rep. Ron Paul (R-Texas). Can he pull off an upset in Iowa? We’ll ask him about his campaign strategy, including his ad attacking GOP rival Newt Gingrich.

Then, a conversation with Rep. Michele Bachmann, who calls herself the “only real conservative” candidate in the race. Do primary voters agree?

We turn to Congress and foreign policy with the ranking member of the Armed Services Committee, Sen. John McCain (R-Arizona). We’ll ask the former Republican presidential candidate about fragile relations with Pakistan and the battle over extending the payroll tax and unemployment benefits.

We end the show with an analysis of some promising economic indicators. Sign of economic recovery, or is it too quick to judge? We ask our expert panel of Alice Rivlin, Douglas Holtz-Eakin, and Ron Brownstein.

It's this Sunday at 9am and Noon ET.
