All very liberal cities.
And in states where unions rule.
True, but that's not the whole story. All those crumbling cities were once major elements of the greatest, most productive, and richest industrial nation the world had ever seen, but now those industrial giants are either dead or dying.
Nations such as the US, Britain, Germany, France, etc, became rich in the Industrial Age by converting their natural resources into salable products and marketing those products to the other nations of the world. Now those "other" nations produce most of those same products at lower prices and sell them to the formerly industrialized nations whose wealth is rapidly being transferred to their former customers.
I recently read that the high tech batteries that power the guidance systems of our military's smart bombs and missiles are bought from a manufacturer in China. When a nation gets to the point where it has to buy essential elements of it's high tech weaponry from a potential enemy nation like communist China it's in big trouble IMHO.
Do you happen to have a list of the top 10 conservative cities?
