This indicates that Hillary is slipping.
If she has to struggle for Minnesota as Nate Silver suggests with her only having a 79.4% of willing the state, she is going to lose nationwide like Mondale in 1984.
I don’t believe MN is in play. A state that has such a solid democratic history will not change its stripes, considering Trump is now slipping backwards in most polls. If all the polls are wrong as some say on this site, then this poll must be wrong and the race probably is not that close in MN.
