The 2008 West Virginia Democratic presidential primary took place on May 13, 2008 with polls closing at 7:30 p.m. EST. It was open to Democrats and Independents. The primary determined 28 delegates to the 2008 Democratic National Convention, who were awarded on a proportional basis. West Virginia's Democratic delegation also included 11 unpledged "superdelegates". The primary came late in the nomination race. Hillary Clinton won by a very wide margin, but her opponent Barack Obama maintained a substantial lead in the overall number of pledged delegate votes.
