“...there has to be massive corruption in their election process...”
Probably, but there is less corruption in the polling. Minnesota is the only state that didn’t go for Ronald Reagan which should give you some idea of the intellect of the average Minnesotan. They must be a bunch of moron farmers, since the RAT party there is called The Democrat Farm Labor Party (DFL).
The Democrat Party was too conservative for Minnesotans, so it got absorbed into the more popular Farmer-Labor Party, which only ‘affiliates’ with the right wing national Democrats.
Minnesota is a lost cause.
It's Mpls-St. Paul that vote overwhelmingly Dim, along with Duluth and the Iron Range (steelworkers who long ago forgot why they must vote DFL, but do it anyway.).
It used to be that a Republican needed a passport to travel up there, but that seems to be changing.
