Well, that's a matter of opinion.
In any case, I hope Republicans are foolish enough to contest Minnesota. It would never make the 270 electoral vote difference. Thus, it's not a real swing state, it would only be the icing on the cake of a Republican landslide on the measure of 2008.
http://republic3-0.com/why-minnesota-will-crown-hillary-clinton-in-2016/There was actually an article 2 months ago that predicted Minnesota would provide Hillary the 270th electoral vote. Lincoln Park Strategies has some kind of model, seems mostly demographic based, that predicts that Hillary would get 52.8% of MN's vote, just 0.2% better than 2012. On the other hand, Iowa, New Hampshire, Colorado become more firm Democrat, with over 53%.
I don't think their model anticipated Hillary's private email server, but besides that, it was kind of cool seeing this close poll, and thinking about their article weeks back.
