Wisconsin and PA will turn Red in coming elections, as will Michigan, and believe it or not, even Minnesota will be red too... When exactly? Can't say, but provided the Dems continue their path to turn the US into a "secular socailist democracy" and the Republicans continue to put up solid candidates.. the midwest will become as RED and reliably so as the south, with perhaps the exception of IL, due to the liberal bastion of Chicago.
The Midwest, and MidAtlantic states are going through the shift that the south went through already..... The population of the remaining blue states will continue to decline as they did in the last census, while the growing economies of the south and other red state areas will continue to increase the red states electoral influence.
The Democrats must reject the radical socialist secular democracy and other fringe groups they now embrace wholey if they desire to ever truly be anything but an obstructionist party again.
Yours is the best analysis yet.
