Larry Sabato, a politics expert at the University of Virginia, said the debate had not dramatically changed the race, but that it could raise some concerns about Sanders and, as a result, shore up Biden’s waning support in the state. “Sanders gave as good as he got,” Sabato said. “But one caution: South Carolina voters probably watched in large numbers. They heard a lot of things about Sanders they didn’t know – and some won’t like what they heard.”
