People living on the fringes of reality have been promoting this stuff for years. Far-right wingnuts were predicting Bill Clinton would declare martial law at the end of his second term, cancel the elections of 2000, and become a dictator. Far-left loons predicted the same thing in 2008. Bush would declare martial law, cancel the election and become a dictator.
The P.T. Barnums of the world know these loons are out there and that there is money to be made from their paranoia. Thus we have Alex Jones, John B. Wells, Glenn Beck, Clyde Lewis and others contaminating the public airwaves every day.
BTW, if you object to this kind of delusional radio George Noory wants you to know you're a loser, a hater and a lowlife.
