This video is from 2009 when Michael Moore came out with Capitalism ,A Love Story. This is the clearest description of what Bernie Sanders' position on Capitalism and Democratic Socialism is.
Contrary to the insider beltway meme being promoted by Chris Matthews and some on DKos, being a Democrat doesn't mean that you have to swear allegiance to the free market neoliberal economic theory of predatory capitalism, also called "El Model" or "The Washington Consensus".
We will see the video of Bernie Sanders' explanation as well as why Chris Matthews MUST attack this position.
