The pall of Nevada's Democratic State Party convention is hanging over the final days of the Democratic presidential nominating contest.

Supporters of Sen. Bernie Sanders shouted down convention speakers, threw chairs and later lodged death threats against state party chairwoman Roberta Lange after the convention awarded Clinton more delegates than Sanders. The state party warns it could be a template for how Sanders supporters could disrupt the Democratic National Convention in Philadelphia. It's also a warning sign to Democrats who will need support from Sanders voters to defeat Donald Trump in November.

Trump has made a point of trying to woo Sanders voters. The Vermont senator has responded with fierce criticism of the presumptive Republican presidential nominee.
