David Barton has officially endorsed Barry Smitherman, current chairman of the Texas Railroad Commission, to be the next attorney general of that state. Smitherman, among many other extremist views, is an advocate of secession. He’s also defended a white supremacist group founded by a neo-Nazi and objected to them being labeled a hate group. There simply is no such thing as a fringe in conservatism anymore. There is no limit to how loathsome, racist or extremist you can be and still be welcomed as part of the Republican coalition.
