Mitt Romney may have won the popular vote in the Michigan primary last night, but he didn’t win more congressional districts. In fact, Rick Santorum won as many of Michigan’s congressional districts as Mitt Romney did (seven each), so both candidates will equally split the 30 Michigan GOP delegates and get 15 delegates. Basically the Michigan primary ends in a tie if you use the delegate allocation to track who “won.”
Mitt Romney may have won the overall vote by a margin of 3 points , but Michigan awards it’s delegates based on how the candidates did in each of the state’s 14 congressional districts, not solely on the popular vote totals.
The system works like this: the winner of each Congressional district gets two delegates. Two additional delegates are awarded based on the overall statewide vote — one delegate for the first place winner and one delegate for the second place winner if he gets more than 15 percent of the popular vote.
