I deleted my initial response to this thread, because after looking at the actual numbers I was wrong in claiming Minnesota was effectively out of reach for the GOP barring something approaching A 1988 level national victory margin. Obama's statewide margin of victory last time was approximately 7.7%, almost exactly double his national popular vote margin of approximately 3.85%.. if the Republicans were to win the popular vote nationally by only about the same unimpressive margin Obama did, and assuming - - a big if I know - - Minnesota followed suit, then the state would then be on the Razors Edge of flipping.
Mind you, Republicans need to understand that anything less than an Obama 2012 victory margin nationally almost surely means Hillary will carry MN.
If MN trended D, I'd be surprised. If it trends R by even one point, it would be won by as great a margin as NC in 2012 with an Obama 2012 sized victory.
