National Presidential Primary County and State Maps (1912-2020)

When looking at these primary maps, its almost as if Obama/Clinton and Romney/Santorum look like the same urban/rural split.

One trend we're seeing that's very interesting is that well-off suburbs and urban areas are going way more to Clinton than Sanders. Even though places right outside Boston are very liberal, high socioeconomic status voters are more pro-establishment, probably because they don't feel the economic pain that people who are in less comfortable positions do. Very liberal places like Hanover, NH and Ann Arbor, MI were much less pro-Bernie than I expected. I honestly expected the Boston area to be much more for Sanders than it was, but the same kind of trend took place in the Detroit area, and I expect the same kind of thing in other metropolitan areas. This primary may be just as much about class as it is about ideology.

Alaska was a sweep for Bernie no matter if you look at districts, census areas, etc.

Detroit is... colorful.

cinyc, is it safe to assume most of that yellow in the Republican map is Cruz? The keys for 10-30% Trump and 50-70% Cruz look very similar.
