Warner will highlight his economic success as governor on a night when the convention’s theme is "Renewing America’s Promise."

Clinton has often been reported to be the keynote speaker, and many viewed it as a way to placate the former first lady and her supporters.

Clinton and Obama battled for the nomination until the last primary and many observers believe that tensions remain between the two camps.

Many of Clinton’s supporters believe that she was not treated fairly in the process by the media and party rules. In addition, another group of people had held out hope that Obama would put his primary rival on the Democratic ticket in an effort to unify the party.

During the convention, some of Clinton’s supporters are organizing events to highlight their misgivings.

The New York senator is still scheduled to be Tuesday’s “headline” speaker.
