I am what is considered an expert, or successfully experienced politico in the upper midwest. Lobbying is a very big part of my business. So, I have to be on top of politics, certain business trends and public opinion. No way in hell Trump wins Minnesota and no way in hell should he be campaigning there when he is closer in other states that are battlegrounds.
Minnesota, which has 5 of it's 8 Congressional seats are held by Democrats. 3 of those 5 seats are women, including a very liberal high ranking senior MoC, a Muslim hated by Trump, and a suburban rep one who identifies as a lesbian. The other two women represent parts of the suburbs too. One man represents not just the western suburbs, with some of the highest end suburbs in the upper Midwest (I'm talking homes with helicopter pads), the other guy -( that I learned everything about sugar beets, soybeans and ethanol) has one of the largest (land wise) and most rural districts in the country.
So, that covers the urban, suburban and rural parts of Minnesota. Statewide, two women are elected to the Senate- Amy Klobuchar is one of the most popular elected officials in Minnesota. Keith Ellison, the first muslim elected to Congress, is the Attorney General now. The people who elected these officials, will not elect a Donald Trump talking about the suburbs are in danger, and muslims are dangerous.
Minnesota holds the title of the state to vote for the Democratic Presidential nominee more consecutive times than any other state. The Republican to fool the voters of Minnesota was Richard Nixon in 1972 (mostly because favorite *******, former VP Hubert Humphrey lost the nomination, after winning the popular vote, to next door rival George McGovern). The only state that never went for Reagan. Trump is no Reagan. This is the last state (maybe Hawaii) a Republican should try to flip. Every second there, takes away from seconds in PA, GA, NC, FL, MI, WI or even IA.
The question remains, why waste time and money there, when he is losing in places that he needs? It appears that he's given up on the idea of actually winning, and just want to have rallies, and then try and provoke civil unrest and cheat.
