Historically of the Michigan-only polls, EPIC/MRA leans Democratic and Mitchell Research leans Republican.
However, the Michigan Governor polls of late have been really erratic, ranging from Granholm/Devos tied to Granholm up +10 and more. Nothing in-between.
I'd believe this is simply a run of odd samples if the Stabenow Senate polling was equally strange, but it hasn't been.
It could just be a volatile electorate in Michigan because of the economy. It's my best guess.
But I think the smart move right now is to ignore all polls from Michigan and wait a while.
