Mitt Romney's decisive victory in Arizona on Tuesday won him every one of that state's 29 delegates in what was a winner-take-all election. But it was quite a different story in Michigan.

Even though Rick Santorum finished 3 percentage points behind Romney, Santorum ended up with the same amount of delegates: 15. That's because Michigan awards most of its delegates according to congressional districts.

Every one of the 10 states voting next week on Super Tuesday will also award delegates on a proportional basis.
