On many levels the convention here in Denver is all about unity. Senator Hillary Clinton used that word nine times this morning. "The Democratic Party is a family, and this is like a big family reunion," says Clinton.
The message over the next four days here in the Mile High city is relatively simple: it is to relay Obama's American story.
Valerie Jarrett, Obama Family Friend, says "He's so authentic. People always ask what's he really like and I say he's same person you see on the campaign stump."
But the 45th Democratic National Convention is about more than the Obama's. A highly-anticipated moment tonight: not only a video tribute to Senator Ted Kennedy, but the senator, who is battling brain cancer, will appear to show his support for Obama.
