Edwards' surprise appearance at a rally Wednesday steered some of the attention away from Hillary Rodham Clinton's landslide win over Obama in Tuesday's West Virginia primary. Despite the victory, the former first lady faces long odds in trying to deny Obama the presidential nomination.
Edwards had been their chief rival from 2007 through last January. But after finishing second to Obama in Iowa, the former North Carolina senator and 2004 vice presidential nominee placed third in the next three contests, then left the race.
Obama and Clinton immediately sought his support, but Edwards stayed mum until Wednesday. The endorsement would have carried more clout had Edwards made it months ago, when the outcome of the Democratic contest was very much in doubt
