Fascinating podcast that talks about the geography of the anti-McCarthy caucus. If you haven't read American Nations, I highly suggest it. It is a very useful lens to view US History and politics.
The best part of this particular episode is evidence of regional drift of Appalachia into that Midlands and Tideland regions based on the politics of the last few days
