Minnesota is a “pretty unique” place (the Dakotas share many characteristics)
many, many good solid Christians who detest the corruption, lies, and anti=Americanism displayed by the current Washington regime
on the other hand, a pretty strong far leftist streak in the DFL (Democratic Farmer Labor Party, essentially an agrarian populist movement with some very strong communistic/socialistic traditions)
combine the two and you get unpredictability
... usually D wins BUT... not necessarily!
appeal to the core honesty and yes, patriotism of the Democratic party base ......and many of them are winnable for Trump
there is also a very strong commitment to fairness (part of the honest ethic)....and the GROSSLY unfair DNC fake prosecutions, slanders, and attempts to interfere with Trump’s campaign....are all STRONG motivators for Minnesotans to vote for him. Very strong motivators indeed.
I think MN may well vote for President Trump now.
Biden will win MN, but it might be close again.
