It's official: The Democratic convention's organizing committee has just sent out a press release confirming that Barack Obama will be giving his acceptance speech in Denver at Invesco Field, a football stadium that holds 76,000 people, instead of the official convention hall at the Pepsi Center.

Obama previously spoke to a rally of about this size in the run-up to the Oregon primary, so there's no doubt he could fill the stadium for his acceptance speech. The size of the event will also spotlight just how wide his support is, with a crowd size that is nearly unheard of in American politics.

But what if it rains? We're checking to see whether the stadium has a dome -- more on this in a sec.

Full press release after the jump.

OBAMA TO ACCEPT PRESIDENTIAL NOMINATION ON
CLOSING NIGHT OF 2008 DEMOCRATIC NATIONAL CONVENTION
IN FRONT OF A CROWD OF MORE THAN 75,000

Final Day of Convention Program to Move to Denver's INVESCO Field at Mile High

DENVER - Breaking the mold of traditional political Conventions, the Democratic National Convention Committee (DNCC) today announced that Senator Barack Obama will accept the Democratic nomination for President of the United States at Denver's INVESCO Field at Mile High. INVESCO Field can accommodate more than 75,000 people and will be the site of the 2008 Democratic Convention's final day of programming on Thursday, August 28, 2008.

"The Democratic Party is nominating a true change candidate this August, and it is only fitting that we make some big changes in how we put on the Convention," said Governor Howard Dean, Chairman of the Democratic National Committee (DNC). "Senator Obama's candidacy has generated an enormous amount of excitement and interest, not only in the Democratic Party but also in the 2008 Convention. By bringing the last night of the Convention out to the people, we will be able to showcase Barack Obama's positive, people-centered vision for our country in a big way."

"Barack Obama's campaign for change has inspired millions of Americans and brought people into the political process who might never have been involved," said Convention Co-Chair Kansas Governor Kathleen Sebelius. "This change in the Convention program will allow thousands of first-time participants a chance to take part. I can't think of a better Convention finale for our nominee who has made reaching out to voters a hallmark of his campaign."

"When we said we wanted to 'bring down the walls,' open up this Convention like never before and truly speak to the American people, we meant it," said Leah D. Daughtry, CEO of the DNCC. "On August 28, we will offer grassroots Democrats, who have turned out in record numbers this year, the opportunity to witness history shoulder to shoulder with thousands of Americans standing up for the change our country desperately needs."

"Senator Obama and the DNCC have truly brought the community into the Convention," said Colorado Governor Bill Ritter, Jr. "This decision will enable thousands of residents from Colorado, the Rocky Mountain West and across the nation to witness history first hand. What a way to fire up our grassroots activists as we head into the fall campaign."

Primetime Convention activities Monday, August 25 through Wednesday, August 27 will continue to be held at the Pepsi Center. The final day of the Convention on Thursday, August 28, including the nomination acceptance speech of Senator Barack Obama, will be held at INVESCO Field at Mile High, also located in downtown Denver. Daytime Convention events, including meetings of the Democratic caucuses and councils will continue to be held at the Colorado Convention Center.

The DNCC announced today that a special block of "Community" credentials will be reserved for Colorado residents for Thursday night's program at INVESCO Field. Details about how to sign up and receive a "Community Credential" for the last night of the Convention will be released in the coming weeks.

"This is the type of Convention people will want to experience together with family, friends and neighbors, and we hope this move enables thousands of Americans to come together, experience history and put Senator Obama on the path to victory in November," Daughtry added.
