Sen. Bernie Sanders (I-VT) won the Vermont, Colorado, and Utah Democratic primaries on Tuesday night, as his rival Joe Biden clinched key victories across the South. Sanders had started off strong in the early states, taking second place in the Iowa caucuses and winning both the New Hampshire primary and the Nevada caucuses. The senator had a second-place showing at Saturday’s South Carolina primary, which Biden won after gaining over 48 percent of he vote. According to the Associated Press, over 85 percent of Vermont—which has 16 delegates—voted for Sanders over Hillary Clinton in the 2016 Democratic primary. Sanders also won the 2016 Democratic primaries Colorado and Utah—which has 67 delegates and 29 delegates, respectively.
