I don't see much bumpitude from last night's results. Even his own "victory" speech, he had to admit that they didn't win Michigan by much. If anything, I think it secured Santorum's position as the anti-Romney, given how poorly Gingrich fared.
Delegate-wise, Romney came out of Michigan with 14, Santorum with 12. Romney got all 29 of Arizona's, but they're small fry compared to a number of other states.
It'll take a couple of days for the state polls to catch up with any carryover effect from the MI/AZ elections. But my guess would be that'll you see a slight (1-2%) intensification for the front-runners in the states where we have some recent poll data (i.e. Santorum gains slightly in Ohio, Romney gains slightly in Massachusetts). I don't know that that holds true for Gingrich in Georgia. At some point, people have to realize that Newt's ship has sailed.
In the absence of poll data on most of the Super Tuesday states, my gut reaction would be to say Santorum wins Alaska, Idaho, North Dakota, Oklahoma, Tennessee. Romney wins Massachusetts, Vermont and Virginia. I think Gingrich makes his heroic last stand in Georgia, but then is finished as a relevant candidate. No idea on Wyoming -- it's rural as all hell, which favors Santorum, but it's also a Rocky Mountain state, which typically has favored Romney because of at least some Mormon population and the higher name recognition. But then, that didn't save him in Colorado, so who knows?
The other issue is that these races are almost entirely proportional, so it's tough for either one of them to run away with this thing. Even if Santorum wins 6 states to Romney's 3, the overall delegate lead will probably still remain with Romney, although smaller.
