DENVER - In a speech that many are calling historic, Democratic presidential nominee Barack Obama spoke to more than 80,000 people at Invesco Field in Denver, Colorado.
He's the first African American candidate to be nominated by a major political party.
A Political High
The weather outdoors was picture perfect and for Democrats here inside the home of the Denver Broncos, feelings were running a mile high.

The star of the show, Obama, came to claim the Democratic nomination with his emphatic message of change.
"Tonight, I say to the American people, to Democrats and Republicans and Independents across this great land - enough!" Obama said.
Obama and the Democrats are tired of the Bush years and Obama took John McCain to task for being part of it all.
"Senator McCain likes to talk about judgment, but really, what does it say about your judgment when you think George Bush has been right more than 90 percent of the time?" Obama challenged.
Obama: Patriotism Has No Party
Obama had a few challenges to meet in this speech. His patriotism has been questioned by some in the McCain campaign.
E-mails circulating on the Internet detail how in the past he wouldn't wear an American flag lapel pin. He now wears one.
And there have been false rumors that he's Muslim.
Competing against an American war hero like McCain puts the pressure on Obama to show he's just as patriotic. He used the word America a whopping 52 times.
"Let us agree that patriotism has no party," Obama said. "I love this country, and so do you, and so does John McCain."
He added, "So I've got news for you, John McCain. We all put our country first."
Obama Explains 'Change'
Obama's other main challenge was to lay out his change agenda. He's been criticized for not offering enough detail.
"Let me spell out exactly what that change would mean if I am President," Obama said.
And indeed he laid out his policy goals on topics like healthcare, energy and taxes.
"I will cut taxes - cut taxes - for 95 percent of all working families," he said. "Because in an economy like this, the last thing we should do is raise taxes on the middle-class."
Throughout this campaign, Obama has not backed down to the more experienced McCain on foreign policy.
In his speech, he turned up the heat lashing out at McCain for concentrating more on Iraq than Afghanistan.
"John McCain likes to say that he'll follow bin Laden to the Gates of Hell - but he won't even go to the cave where he lives," Obama said.
'Yes We Can' versus 'I Have a Dream'
Obama's speech comes on the 45th anniversary of Martin Luther King's 'I Have a Dream' speech.
With 84,000 people looking on to witness the first African American to accept a political party's nomination, the historic moment was not lost on those attending.
"It's the spectacle that just awed me," Fox News commentator Juan Williams said. "I've never seen anything like it in American politics. I've covered politics for more than 30 years across the country and the idea that a politician could bring people together like this is really awe inspiring."
One attendee said, "I cried actually. I've never been moved to tears in my entire life, and it's overcoming. It's beautiful."
