Obama's 2008 showing there was disappointing. I don't care how "polarized" Minnesota is; there are more polarized states where he got bigger swings. My answer is yes. Not sharply, perhaps not permanently, but as micro-trends go this is a pretty developed one.
We have to acknowledge that McCain advertised heavily in Minnesota at the end of summer for a significant amount of time without a corresponding response from Obama. That kind of disparity in his favor was very rare in '08 and showed results in Minnesota polling. If it moved 2 points to McCain, would that explain a lot?
