Sen. Hillary Clinton (D-N.Y.) attended a Mother's Day celebration in Manhattan Saturday and vowed to stay in the race despite Sen. Barack Obama?s (D-Ill.) lead in superdelegates.

Clinton was with daughter Chelsea and more than 1,000 supporters at the Sheraton Hotel for the Mother?s Day fundraiser. However, this week has been a difficult one for the former First Lady.

Obama won a convincing victory in the North Carolina primary and lost Indiana narrowly on Tuesday. Obama has been gaining strength in the days since. On Friday, the Illinois senator picked up the support of nine more superdelegates.The crowd in the standing-room-only event says the race for the White House is far from over. Despite Obama's gains, many of New York's top politicians say they will continue to support Clinton. When Clinton promised big gains in the days to come, the crowd jumped to their feet.

?We will have a unified Democratic Party and we will defeat John McCain," said Clinton.

For many of Clinton?s supporters who attended the event, it was exactly what they wanted to hear.
