http://www.cnn.com/2016/05/17/politics/democrat-bernie-sanders-revolt/ Dems' new fear: Sanders revolt could upend Democratic convention Sen. Barbara Boxer, a veteran of Democratic politics, says she never saw anything quite like this before. Loud cursing, shouting, obscene gestures and vile insults, including crude comments about the female anatomy. It was all on display over the weekend as supporters of Bernie Sanders turned the Nevada State Democratic Convention into chaos. "I was not able to stop these people for doing what they did," Boxer, a Hillary Clinton supporter, told CNN. "Apparently they've done it before. .... This group of about 100 were very vocal, and I can't describe it -- disrespectful doesn't even explain it, it was worse than that." ...many Democrats fear that if Sanders does not rein in his supporters, the same ugly scene that occurred in Las Vegas last weekend could replicate itself in the Democratic National Convention in Philadelphia.
