Sanders Supporters Boo Loudly When Bernie Says ‘We Have Got to Elect Hillary Clinton’

Supporters of Sen. Bernie Sanders (I., Vt.) booed loudly Monday when he said they needed to come together to elect Hillary Clinton president.

During a fiery speech calling for several progressive changes and boasting of the effect his campaign had on the Democratic Party platform, Sanders got around to the woman with whom he fought tooth-and-nail for the nomination and who he finally endorsed half-heartedly at a rally on July 12, leaving his fans none too pleased.

"We have got to defeat Donald Trump," he said. "And we have got to elect Hillary Clinton and Tim Kaine."

The crowd broke into vociferous boos. Sanders tried to appeal to beating Trump as their motivation.

"Brothers and sisters, brothers and sisters, this is the real world that we live in," Sanders said. "Trump is a bully and a demagogue. Trump has made bigotry and hatred the cornerstone of his campaign. Throughout this campaign, he has insulted Mexicans and Latinos, he has insulted Muslims, he has insulted women and African Americans."

Tensions are high within the party after DNC email leaks revealed party officials openly favored Clinton over Sanders, sometimes insulting Sanders and even conspiring for ways to derail his candidacy. Party chair Debbie Wasserman Schultz (D., Fla.) announced Sunday she was resigning her position, and she was booed loudly during her remarks at a Florida delegate breakfast on Monday.
