Incidentally that reminds me, seeing as many groups are constantly prepping for a 'forever nigh' race-war, several factions of supremacists are bound to be alive and kicking. Maybe even thriving in this sort of scenario. Since you brought up Springfield I'm thinking of the Joplin Honkies and Peckerwood Midwest, but I think that the Aryan Circle and Sacred Separatist Group have a foothold in Missouri as well.
