Well it still is one imo(albeit a D leaning one)
It was fairly close in both 2000 and 2004.
Plus the GOP controls the Governorship, State Legislature, as well other constitutional officers for the state such as AG and SS. Plus a majority of the state's House Seats.
Meh, Michigan's 1988 presidential results were the closest to the national result of any state. In 1992, it was grouped in with about a dozen other states that were within a point of the national result. It didn't begin pulling away until 1996; I'd argue that 2000 was the breakaway year. In 2000, 2004 & 2012, the state was consistently about three points more Democratic than the nation as a whole (2.90, 2.97 and 3.03 points, respectively).
