(CNN) - Former Massachusetts Gov. Mitt Romney will win Tuesday's Republican primary in his native Michigan, CNN projects.
The projection is based on precincts reporting results, exit polls and other statistical models - including the number of votes outstanding in areas where Romney is expected to do well.
CNN's Shirley Zilberstein reports from Romney's election night celebration in Southfield, Michigan that the campaign played "Signed, Sealed, Delivered" as the race was called for the former Massachusetts governor when polls closed at 9 p.m. ET.
