My question is… Why do we accept as fact that America's "cities" will naturally turn blue? What is your answer when someone asks you why cities are always blue? "Minorities always vote democrat" Where did this assumption come from?

Go to 2016 detailed results for example "Wayne County" Michigan. Examine each district and adjoining districts. Do "illegals, Hispanics and blacks" only live in big cities and not rural areas and do they all vote democrat 98% of the time? There are not enough minorities in these cities to swing the votes to such extremes.

They have been cheating for the last 100 or more years. Right now in 2020 no one questions how counties like Washtenaw and Wayne county in Michigan can have such extreme opposite numbers from the rest of our state. I have been to those counties multiple times and they look just like the county above it and besides yet in Wayne county 2016 virtually every district was 100% Hillary Clinton.
