The election in 2016 marked the first time since 1952 that the Democratic candidate performed worse in Minnesota than in the nation at large. Hillary Clinton won the national popular vote by 2.1 points but won Minnesota by just 1.5 points, or 44,765 votes. Minnesota has been a primarily Democratic state in national elections since 1932.
The Iron range is blue? Hmmmmm
How big a difference could it make here and in other close states if President Trump made a big bold outreach to Native Americans; say expand tribal economic opportunities beyond and bigger than casinos and expanded fishing rights under previous treaties?
Looking at that map, the issue has been the suburbs - specifically counties like Carver, Scott and Anoka. They are GOP-leaning suburbs but are full of soccer moms who hate mean tweets.
If Trump can raise his numbers in those counties (as well as Dakota and Washington - both blue suburbs), he stands a good chance.
