Mark Blumenthal and Charles Franklin provide a summary of the latest Michigan polling data. To summarize their summary: Things look good for Romney, but Michigan is "certainly still up for grabs." Say a combination of a strong showing among Republicans and - bizarrely - Democrats influenced by Daily Kos helps Romney win Michigan. The Republican campaign would alter dramatically once again, and chances are by the time that South Carolina and Nevada vote this Saturday Romney would be the national poll leader. Romney would have two gold medals and two silvers. He also would have to spring for a trophy shelf where he could put all the medals he's been collecting. And a split result - different winners in Iowa, New Hampshire, and Michigan - would muddy the Republican waters even more, no doubt resulting in a zillion "Whither the GOP?" newspaper stories and magazine covers.
