Nate Silver "No, The system is not "rigged"against Sanders

++Nate Silver at 538 goes to great lengths to explain that Hillary Clinton is winning because more Democrats want her as the nominee--that's in terms of popular vote and delegates.

++Nate goes into the caucus versus primary debate and demonstrates that Sanders benefited from caucus and Clinton benefits from closed primaries to Democratic voters.

++Nate also shows that Hillary's delegate lead if you factored all this in the equation would be about 400+ compared to 250+ at this stage.

++For Sanders to declare a piopular mandate is a long stretch.
