Curtain-Raiser for the Michigan Primary

Tomorrow's Michigan primary has turned into a standoff between John McCain and Mitt Romney. Polls show the race essentially tied, with 40% of Republicans still undecided.  Romney may have been Governor of Massachusetts, but he grew up in Michigan, where his father, George Romney, was chair of the late American Motors Corporation, a three-term governor and a presidential candidate. But with John McCain coming on strong, he may or not be a "favorite son." Juliet Eilperin, who is there for the Washington Post, reports on what could be a decisive political moment.
