State: Minnesota
Type of election: Caucus
How it works: Caucus begins at 7 p.m. It is non-binding and the delegates selected tonight will advance to district or county conventions, which in turn elect state delegates, which then choose national delegates. To participate "attendees must be eligible to vote in the next general election, live in the precinct, and be in general agreement with the principles of the political party." In the end, 40 delegates will be chosen.

Latest polling: Polling for today's contests has been sparse:
Bottom line: Sparse polling makes this one a bit of a toss-up, but it seems likely that Santorum will stay alive after today and Gingrich could be hurt if he finishes last. A Romney victory could help him appear much stronger and help move him towards the nomination quicker.
