How important are Michigan and Arizona to Romney’s campaign? Important enough that the man himself will make a rare Sunday morning appearance on Fox to pitch himself to late deciders. (Santorum, a Sunday morning stalwart, will be on ABC and NBC.) That’s your best bet, especially since Chris Wallace decided to schedule him back to back with Mitch the Knife, whose name you’ll be hearing a lot later this week if Santorum pulls the upset on Tuesday.

If you’re sick of the primary, and everyone is, try the gay-marriage face-off on CBS between O’Malley and Christie instead. The full line-up via the AP:

ABC’s “This Week” — Republican presidential candidate Rick Santorum; Govs. Rick Snyder, R-Mich., and Deval Patrick, D-Mass.

NBC’s “Meet the Press” — Santorum; Govs. Jerry Brown, D-Calif., and Jan Brewer, R-Ariz.

CBS’s “Face the Nation” — Govs. Martin O’Malley, D-Md., and Chris Christie, R-N.J.

CNN’s “State of the Union” — Sens. John McCain, R-Ariz., and Lindsey Graham, R-S.C.; Govs. John Hickenlooper, D-Colo., and Scott Walker, R-Wis.; Robert Gibbs, adviser to President Barack Obama’s re-election campaign.

“Fox News Sunday” — Republican presidential candidate Mitt Romney; Gov. Mitch Daniels, R-Ind.
