Less than a month ago, it seemed inconceivable that Mitt Romney would have to fight for his political life in his home state of Michigan.
But fast-moving economic changes, the candidate's verbal stumbles and event venue blunders, and the ascent of flamethrower social conservative Rick Santorum have left Romney sweating to eke out a win Tuesday in Michigan's Republican presidential primary, where the latest polls show a tight race.
If primaries and caucus victories are still all about media attention and momentum, then, yes, it's critical who wins Michigan's statewide vote Tuesday. All the more so if that winner is not Mitt Romney, who grew up there and whose dad was governor in the 1960s.
But as to collecting actual delegates for the actual GOP nomination? Tuesday's vote in Michigan probably will not matter much at all.
