Obama won Minnesota by 10 points in 2008. This was less than Nevada (12), Pennsylvania (10.3), and Wisconsin (14) — not to mention well below Michigan and Oregon. The differential was roughly the same as New Hampshire.
Given the less unfavorable demographics in Minnesota, it is not surprising that it is in play. I have actually been surprised that we haven’t heard more about it so far.
In addition to the above, the differential of 10 points was roughly the same as Iowa (9.5).
in 2010 Minnesota turned the state senate over to the republicans. Something that had not happened in 20(?)+ years. Dayton won by a very slim margin.
While I think Romney carrying MN is slim. It is possible. It depends on turn out, Ritche (the SOS) and cheating.
