Who won the Democratic debate in South Carolina?

She took Sanders to task for refusing to call for an end to the Senate filibuster, without naming him, and said the filibuster would give the gun industry and oil companies a "veto" over legislation.Yet the caution Warren applied to knocking Sanders marked a stark contrast to the fiery passion with which she attacked Bloomberg, the former mayor of New York, throughout the debate, including for his past support of Republican senators like Scott Brown, whom she defeated in 2012.Warren offered up some humility when asked about the biggest misconception of her: "I never was supposed to be on a stage like this."The former vice president was at his most passionate when he swooped in to disagree with Sanders that his remarks praising Fidel Castro's literacy program were similar to what Obama has said in the past. He said that Sanders' health care math doesn't work and that it "adds up to four more years of Donald Trump, Kevin McCarthy as speaker of the House." Democratic candidates who captured the House, he said, "are not running on your platform — they are running away from your platform as fast as they can." He joined Warren in knocking Sanders on the Senate filibuster: "How are we going to deliver a revolution if you won't even support a rule change?"South Carolina is an important test for Buttigieg where he's weakest — with African American voters, who make up more than half the Democratic electorate. He stood up for his electability by pointing to the many polls showing that "I beat Trump." He argued that to win the presidency, "what you're going to need is an unprecedented grassroots movement of black and white and Latino, Native American and Asian people who are standing up and fighting for justice." He dodged a question about whether he'd move the U.S. Embassy in Israel back to Tel Aviv from Jerusalem.Asked about his past remarks praising Fidel Castro's literacy program, Sanders said, "I have opposed authoritarianism all over the world," but he argued that the U.S. has overthrown governments in places like Chile and Iran to the detriment of global security.
