Bernie Sanders drew boos and angry chants from his delegates as he called for the election of Hillary Clinton.
Many in the crowd chanted, “We want Bernie” as Democrats gathered in Philadelphia to nominate Clinton.
Sanders responded to his supporters with pragmatism; Clinton weeks ago locked up the number of delegates she needs to win the nomination. Sanders said, “This is the real world.” He added that electing Clinton was the way to stop Republican Donald Trump, who he described as “a bully and a demagogue,” from becoming president.
