I was thinking about whether or not ideological sorting is geographically uneven. This was shown when someone said California is more Democratic but Vermont is more Liberal.
The Washington Post wrote an article on state legislatures and how they are polarized. They made a picture on how much polarization there is by state legislature:
I think this has to do with the New England Republicans and Southern Democrats. This is because a lot of New England and some southeastern states are less polarized despite strongly leaning liberal and conservative respectively.
The Midwest, West, and New Hampshire (!) are all of top 10. Is the ideological sorting (liberals being Democrats and Republicans being conservatives) unevenly geographically distributed?
