Hillary Clinton is refusing to give up her run to the White House even as Barack Obama passes her in the race for the all-important super-delegates.
At least three more Democratic super-delegates have pledged to back Mr Obama pushing him ahead of Mrs Clinton for the first time.
Super-delegates are the officeholders and Democratic Party officials who will attend the party’s National Convention in Denver, Colorado this August.
The candidates need the support of the super-delegates if they are to be nominated for the presidency, but the super delegates can choose to support either candidate regardless of primary election results.
The former first Lady is refusing to give up and said challenges only made her more determined.
“I may stumble and I may get knocked down but I will always get right back up, and I will never quit until this job is done,” Mrs Clinton said.
