JF,  I see Sanders more like the McGovern wing of the democrats in 1972.  Sanders missed his opportunity for real change when he declined the Green Party's invitation to lead their presidential ticket this year.  He had an opportunity to have an immediate impact and make the Green Party a viable third party and attract folks from all parties (republicans, democrats, and Libertarians) who see the status quo as leading us into oblivion.  Much like what Gary Johnson and Bill weld are trying to do with the Libertarian Party.  Bernie's decision was opportunity lost for us all.
