Former Massachusetts governor and Michigan native Mitt Romney has won the Michigan primary, edging out rival GOP hopeful Rick Santorum.
At 11 p.m. Tuesday, with 87 percent of the statewide vote counted, Romney carried 41 percent of the vote to Santorum's 37 percent.
Romney's win in Michigan and Arizona propels his campaign towards Super Tuesday on March 6. Ten states and more than 400 delegates will be up for grabs.
