Other highlights on Day 1 of the Democratic gathering:
• Delegates will have a chance to vote for either Barack Obama or Hillary Clinton, as the two agreed to a roll call vote. The deal will allow some states to vote for Clinton, then acclimate to the nomination of Obama.
• Even with the opening of the convention, there remains divisions between Obama and Clinton supporters. But by the end, Speaker of the House Nancy Pelosi, D-Calif., said that "Democrats will leave this Denver convention unified, organized and stronger than ever to take America in a new direction."
• Police in riot gear turned pepper spray on about 300 protesters about a mile from the Pepsi Center, after they disrupted traffic and threw bags with colored liquid at the police. Despite the confrontation, protesters were fewer than expected.
• Union leaders admitted Monday that not all of their members, who are generally staunch Democrats, are supportive of Obama. Part of the reason is his race, but it is also inexperience and unfamiliarity. "It's not the only issue ... but it is an issue," said Karen Ackerman, political director of the AFL-CIO.
• Trying to downplay soaring expectations for his Thursday night speech, Obama said it will not be like his 2004 keynote speech, which catapulted him politically. "I'm not aiming for a lot of high rhetoric," he said after a campaign stop in Iowa. Instead, he said it will be "much more workmanlike."
• Democrats adopted a platform Monday that commits the party to Barack Obama's policy ideas, but also credits his primary rival Hillary Rodham Clinton with putting "18 million cracks in the highest glass ceiling."
• Not everyone was watching the opening night of the Democrats' gathering. "I'm sure there's also a baseball game on tonight," said Tony Fratto, spokesman for President Bush, when asked about Bush's viewing plans.
