First off for the record this poll is two months old, not sure why it was posted now.
Second Minnesota has been trending Democratic across the board. No Republican has won a statewide race since 2006 (Tim Pawlenty). No Republican has gotten 50%+ of the vote statewide since 1996 (Arne Carlson). The rural republican areas of the state are shedding population while the liberal Twin Cities have been booming. Unless there is a Republican landslide nationally Minnesota is safe Democrat for the presidency in 2016.
Okay it is NOT trending Democrat. Lol. PS everyone, Minnesota democrats are typically moderate and fairly conservative on social issues. I see no reason why it is implausible for them to begin voting republican when democrats are increasingly liberal and are isolating white voters.
Minnesota Democrats conservative on social issues? Wow that's news to me and I live here. The state has voted for those noted social conservatives Barack Obama, Al Franken, Amy Klobuchar and Mark Dayton. In addition it was one of the first states to vote against an anti gay marriage amendment.
And yes Minnesota is trending more Democratic and not just at the Presidential level. see my above post.
