"For the latest round of curse-word hurling, chair throwing, social-media stalking and conspiracy-theory swapping, look no further than the supporters of Bernie Sanders.
"Over the weekend, dozens of Sanders devotees lost their minds after the Nevada Democratic Party, meeting for its convention in Las Vegas, awarded a majority of delegates to front-runner Hillary Clinton.
"Convinced that the establishment had rigged the rules and that Sanders delegates had been excluded for unfair reasons, they booed and traded barbs with people on stage, including Clinton surrogate and keynote speaker U.S. Sen. Barbara Boxer.
"The convention ended abruptly, descending into chaos that was captured for the world to relive on Facebook and YouTube.
"Death threats and vandalism followed, prompting Nevada Democratic Party offices to close on Monday and its chairwoman, Roberta Lange, to release some downright disgusting voicemails and text messages she had received from Sanders supporters. She also reported threats against her grandchildren." . . .
