According to The New York Times election map, only three counties in Michigan went for Democrat Virg Bernero over Republican Rick Snyder in the governor's race — Genesee (Flint), Wayne (Detroit), and Gogebic (no idea), way up in da U.P., eh.
UPDATE: Gogebic County = Ironwood. Thanks, Jan.
ANOTHER UPDATE: Washtenaw (Ann Arbor) and Ingham (Lansing) also went Democratic in the end. Whew, I was thinking I'd really lost touch with old Michigan. Thanks, Will.
