Edit: Also, if Santorum is up double digits in Michigan I'm very interested in how Arizona looks.
Yeah, you'd have to imagine that Romney'd be down there as well. True, Santorum is a much more attractive option in Michigan than in Arizona, but I can't see why the typical GOP voter in Arizona would choose Mitt over him either. Mormons can't make up more than, what, 15% of the GOP electorate in Arizona? Their presence may not be negligible, but Mitt's going to need a lot more than the Mormon vote here, I imagine.
