Sen. Hillary Clinton on Saturday rejected calls by supporters of rival candidate Barack Obama to quit the Democratic presidential race, and Obama said Clinton should remain in race "as long as she wants." "The more people get a chance to vote, the better it is for our democracy," the New York senator and former first lady told supporters at a rally in Indiana, which holds a May 6 primary. "There are some folks saying we ought to stop these elections," she was quoted as saying by CNN. "I didn't think we believed that in America. I thought we of all people knew how important it was to give everyone a chance to have their voices heard and their votes counted." Clinton has won primaries in the biggest states so far, but Obama has won more total contests and leads her in the race for delegates to the party's August convention in Denver -- where the Democratic nominee will be formally ratified. Two of Obama's leading supporters, Sens. Christopher Dodd and Patrick Leahy, said Friday that Clinton should rethink her chances of overcoming that deficit and consider folding her campaign. Leahy, of Vermont, said Clinton "has every right, but not a very good reason, to remain a candidate for as long as she wants to." Speaking in Johnstown, Pennsylvania, Obama said he did not discuss Leahy's call for Clinton to drop out with the Vermont senator, who serves as chairman of the Senate Judiciary Committee. "My attitude is that Sen. Clinton can run as long as she wants," the Illinois senator said. "She is a fierce and formidable competitor, and she obviously believes that she would make the best nominee and the best president. I think that she should be able to compete, and her supporters should be able to support her for as long as they are willing or able." Pennsylvania is the scene of the next Democratic primary, on April 22, and is the largest state that hasn't weighed in on the party's presidential race.
