The Obama campaign is trying to avoid hard feelings among Clinton's supporters at their carefully orchestrated convention. But they still haven't reached a deal on whether Clinton will be included in the roll call vote for the nomination, which could make the party appear divided heading into the final stretch of the White House race.
The campaign said Obama's wife Michelle is slated to headline the opening night on Aug. 25, while the yet-to-be-named vice presidential pick will speak on the third. Democratic officials say Bill Clinton is also scheduled to speak that night, but only the headliners were in Sunday's official announcement.
Obama is expected to become the party's first black presidential nominee on the fourth and final night as the convention moves from the indoor Pepsi Arena to a bigger venue at Invesco Field at Mile High stadium. It happens to be the 40th anniversary of Martin Luther King's "I Have a Dream" speech.
