BREAKING NEWS: The Republican primary in Michigan remained too close to call as polls closed, but NBC News projects Mitt Romney will win the Arizona GOP primary, according to early exit polls. 

Romney’s Arizona triumph came in a race that was scarcely contested, and he pocketed all of the 29 Republican National Convention delegates at stake.   

Michigan was as different as could be.  Stay tuned for that call.
