Mitt Romney and Rick Santorum apparently each won seven of Michigan’s 14 congressional districts — where most of the delegates to the national convention are allotted based on the state Republican Party’s rules — in Tuesday’s GOP presidential primary.

With 99% of the vote counted, Romney won the state’s overall vote, 41- 38%.

Though results are not yet final, Santorum appeared to make it even in the battle for congressional districts by taking the last district to report its numbers — the 13th in Detroit and some western Wayne suburbs.

Santorum had 9,481 votes in the district to Romney’s 7,946, while Ron Paul had 6,305. Democratic organizations in the congressional district urged their members to vote for Paul to try to keep Romney from winning the district.

So it wasn't much of a Romney victory at all in fact. A tie, which IMO is really a loss for Romney considering he should have done better in this state. It doesn't bode well for his future chances if he does eventually win the nomination.
