A handful of Bernie Sanders’ delegates are placing part of the blame for Monday night’s revolt on the Vermont senator, saying his campaign did not properly communicate with the legions of politically inexperienced delegates who went into the convention with unrealistic expectations.The first night of the Democratic National Convention was a raucous scene in which boos overwhelmed speakers at seemingly every mention of Hillary Clinton’s name, creating the image of a party in chaos.The discord was partially fueled by the leak of a trove of emails showing that the Democratic National Committee actively tried to undermine Sanders during the primary — evidence that vindicated seething Sanders supporters convinced the system was rigged against them.But it was also the result of some dumbfounded delegates who went into the convention thinking Clinton didn’t have the nomination sewn up, and that there was still a path for Sanders.The first day proved to be a rude reality check.“The Sanders campaign was doing an excellent job on negotiating on the platform and the shape of the convention, but it could have been a lot better in preparing the delegates,” said Daraka Larimore-Hall, a Sanders delegate from California.
