Only that they're following the *vote with your feet* precedent and methodology established by Jason Sorens and the NH FSP Porcupines, circa July 2001. [ Announcement: The Free State Project The Libertarian Enterprise, July 23, 2001. Or, so far as that goes, the Latter-Day Saints in Utah.
But there are several other thriving FSP spinoffs as well, including the Free West Alliance and the Free Wyoming Project. And there's a similar effort in Texas to restoring Texas sanity to a county or tri-county area there, as well.
Doesn't promoting this kind of thing without a mention of the FSP hurt the FSP, though? I would consider Christian Exodus if I didn't know about FSP, just as I would these other groups you mention.
Sure will be interesting watching the federmaniacs trying to squelch these types of movements from my mountain top retreat, and they'll try just as sure as God made little green apples.
Good hearing from you, archy. ;^)
