The 2008 Michigan Republican presidential primary took place on January 15, 2008. Mitt Romney came in first with 39 percent of the vote, followed by John McCain with 30 percent and Mike Huckabee in third-place with 16 percent. The victory was widely viewed as critical for the Romney campaign, as a loss in Michigan, where his father was governor, would have resulted in a loss of momentum after two losses already in New Hampshire and Iowa.
National delegates determined: 30 out of 60
In accordance with Republican National Committee rules, Michigan was stripped of half its delegates for holding primary contests before February 5, 2008.
15 statewide delegates were awarded proportionally to candidates who got 15% or more of the vote. Each of the state's 15 congressional districts received 1 delegate, which was awarded to the candidate who got the most votes in that district.|+100% of precincts reporting[1] |-! Candidate! Votes!
