Mitt Romney won the Michigan Republican primary on Tuesday, beating back a tough challenge by Rick Santorum in Romney’s birth state. By winning, he grabs momentum going into next week’s Super Tuesday contests.
With more than 70% of the vote counted, Romney led 41% to Santorum’s 37%. Ron Paul had 12% and Newt Gingrich 7%.
Romney appeared to win with large support in metro Detroit, outweighing Santorum’s lead in other parts of Michigan. Romney also won Arizona’s primary earlier in the night.
