Don't people tend to change party when they move from cities to rural, and vice versa? So we could also end the Democratic party as we know it by convincing more people to move out of cities.
Which comes first? People start to have ideas that the city living isn't working out for them because they don't like X, Y, and Z and once they move, they realize that means they are now more red than a decade ago?
Or blue-no-matter-who Democrats move to a rural area and then change their beliefs?
I suspect it's more the former than the latter (you move after your beliefs change more than before).
As someone who grew up rural and has spent most of his adult life in cities, IME people change when going rural → urban, but don’t going the other way. Those who “change” after going rural tend to be those who previously straddled the fence in the city.
