Earlier in the day, Terry McAuliffe, one of Clinton's staunchest supporters and chair of her failed presidential campaign, seemed confident unity was near.
"Her speech, Bill Clinton's speech tomorrow - boom - we're there," McAuliffe told Rick Klein and Sam Donaldson Tuesday during their live coverage on ABC News Now.
Last week the once rival Democratic camps agreed to place Clinton's name into nomination in order to mollify her supporters, still bitter after a divisive five-month long primary battle.
But as the convention got underway, party leaders aborted that plan in an attempt to avoid any televised public displays of disunity during the roll call.
The first 30 minutes of Wednesday's convention program will be devoted to nominating and seconding speeches for Obama and Clinton. After a roll call begins, the Obama and Clinton camps have agreed that the roll call will halt at some point and the convention will move to nominate Obama by acclamation.
While the last throws of the Obama-Clinton drama played out, several speakers attempted to guide the narrative back to Obama versus McCain on the economy.
In his keynote address tonight, former Virginia Governor Mark Warner linked McCain to President George Bush.
"The fact that this president never tapped into our greatest resources -- the character and resolve of the American people. He never asked us to step up," Warner said, arguing McCain "promises more of the same."
Kansas Gov. Kathleen Sebelius reminded voters watching at home that McCain couldn't answer a reporters' question last week on how many homes he owns.
"Now I'm sure you all remember that girl from Kansas who said there's no place like home. Well in John McCain's version there's no place like home, or a home, or a home, or a home."
Illinois Congressman Rahm Emanuel, a former Clinton aide and close Obama friend, I'm from Chicago, the home state of the next president of the United States."
"There is only one candidate from the middle class, that understands the middle class, and that can deliver the change the middle class needs: Barack Obama," Emanuel said.
"John McCain is right. He doesn't understand the economy as well as he should," said Arizona Gov. Janet Napolitano.
"Obama wants to export our products, not our jobs," offered Michigan Sen. Debbie Stabenow.
Former top Clinton supporter Pennsylvania Gov. Ed Rendell slammed McCain on energy, though he left out of his remarks that Obama voted for President Bush's 2005 energy bill and McCain voted against it.
"The only thing green in John McCain's energy plan is the billions of dollars he's promising in tax cuts for oil companies. And the only thing he'll recycle is the same failed Bush approach to energy policy," Rendell said.
The economy was the topic of Pennsylvania Sen. Bob Casey's speech, but his words on abortion gained attention.
"Barack Obama and I have an honest disagreement on the issue of abortion. But the fact that I'm speaking here tonight is testament to Barack's ability to show respect for the views of people who may disagree with him," Casey said.
His invitation to speak at the convention came 16 years after his late father, former Pennsylvania Gov. Bob Casey, was denied a convention speaking role because of his anti-abortion views and was perceived as an olive branch to those voters.
