Plausible and worrying
No rating since I haven't read the entire book, just the short story The Bookstore at the end of America (available from tor). It's a worrysome thought experiment about what happens when the eventual second civil war splits the US along ideological lines and asks if it is possible to straddle that border. I'm not sure if it will be.
