Speaking as someone who lived in MN during the "Ventura Administration", yes, he is batshit.
I have no idea why a network would give him a stage in which to show exactly how batshit he is.
I guess we have to assume that the network believe that there is an audience out there for this type of "entertainment". I have no interest in "Real Housewives" or "Jersey Shore", but they seem to be pretty popular as venues for people willing to display their odd, bad, and/or crazy behavior! Ventura and Beck are just two more flavors of crazy that I have no appetite for....
