Bill Clinton, former U.S. President and husband of former U.S. Secretary of State and 2016 Democratic presidential candidate Hillary Clinton, speaks to the crowd, during a town hall event at the Columbia Museum of Art Boyd Plaza in Columbia, South Carolina, U.S., on Friday, Feb. 26, 2017. As South Carolina prepares for Saturday's Democratic presidential primary, Clinton's quandary is how to win over young voters -- particularly women -- when the enthusiasm she needs in a general election is so linked to support for her 74-year-old white male opponent.
