The more northern you go, the more left-leaning the independents are. That is to say that new england independents are really democrats, and that counts for some midwestern states like MN, WI, and MI.
I really don’t pay much attention to polls, but this particular pollster is usually spot on.
If the state made it as simple as checking a box at the top, the Dems would have the largest total.
PPP (D): Obama up 42-38 with Indies in Michigan.
Quinniapiac: McCain up 44-41 with Indies in Michigan.
Detroit News: McCain up 4 (no firm number) with Indies in Michigan.
This poll, Obama up 17 with Indies in Michigan.
Again, seems very, very suspicious to me.
