The Bundy's are neo-Bircher Armageddonist authoritarians who think ranchers be allowed should seize public lands for themselves so they don't pay grazing fees (and pushes Soverign citizen rhetoric as a poorly-cloaked pretext). That's proof of a current in Idaho, but it's not the current you think it is. Case in point, if you read the Turner Diaries, some "libertarian" arguments are used against the System, but it certainly isn't a libertarian story.
It fits in the sense that American "libertarians" are extremely Hitlerite.
