With 26 of the state’s 30 delegates decided, Romney and Santorum each have 13. Michigan awards most of its delegates based on results in each of its 14 congressional districts — handing out two for winning each district.
Results were incomplete in the final two congressional districts as of this afternoon. But with 98 percent of the precincts reporting, Santorum had a slight edge in both. If his lead holds in both districts, Santorum would win a majority of the state’s delegates, or 17 to Romney’s 13.
Santorum won Michigan's 2nd Congressional District, which includes Ottawa County, 47 percent to Romney's 36 percent. Santorum also beat Romney in Ottawa County, 49 percent to 35 percent.
John Brabender, senior adviser for Santorum’s campaign, told reporters Wednesday that he expected Michigan’s delegates would be split evenly between Romney and Santorum. The candidate himself predicted as much, too.
“We’re going to walk out of Michigan with 15 delegates, and he’s going to walk out of Michigan with 15 delegates,” Santorum said, campaigning in Powell, Tenn.
Romney won all 29 delegates in Arizona’s primary Tuesday.
Newt Gingrich and Ron Paul were shut out of delegates in Tuesday’s contests.
In the overall race for delegates, Romney leads with 165, including endorsements from Republican National Committee members who automatically attend the convention and can support any candidate they choose. Santorum has 85 delegates, Newt Gingrich has 32 and Ron Paul has 19.
It will take 1,144 delegates to win the Republican nomination for president.
