Art Robinson, of Oregon Petition fame is running for Congress. Peter Sinclair has Robinson's interview by Rachel Maddow. Robinson comes across as more than a little nutty -- rather than elaborate on his views on hormesis (radioctive waste is good for you!) he just insisted that quotes from his own writing were lies in some unspecified way. Also of interest is Sinclair's latest Crock showing a simple experiment to demonstrate the effects of CO2 on the atmosphere.
