Ed Schultz will be in Vegas tonight for the first Democratic debates. Ed provides commentary on what he anticipates occurring, and also comments on the DNC Vice-Chair being uninvited to the event because she was critical of the number of debates this election cycle. Democratic Strategist Bob Shrum joins Ed to preview what we can expect from the debate, and what is at stake for each of the candidates. Rep. Keith Ellison, D-MN, joined Rep. Raul Grijalva, D-AZ, in endorsing Sen. Bernie Sanders prior to the debate. John Nichols from the Nation joins Ed to discuss the importance of these congressional endorsements.
