Mitt Romney is hoping to triumph in the Michigan primary on Tuesday, while Rick Santorum aims to score an upset win over the former Massachusetts governor on his home turf.
HuffPost's Jon Ward reports on the delegate situation in the Wolverine State, where Romney was born:
In Michigan, 28 of 30 delegates will be awarded by congressional district. Candidates will earn two delegates for every congressional district in which they win the most votes. There are 14 districts, and the remaining two delegates will be awarded based on who wins the most votes statewide.
The outcome of the race is likely to be close, according to the latest polls. Ron Paul and Newt Gingrich go into the contest running behind Romney and Santorum by a sizable margin.
The Arizona primary will also take place on Tuesday.
