The Liberal Bastions of Flint, Detroit and Gogebic?
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.
