Obama offers backstage access

For Obamamaniacs, this would be like winning the lottery.

Barack Obama announced this afternoon, via a video message, that 10 supporters and one guest each will get an all-expenses-paid trip to Denver next month -- and will get backstage access at Invesco Field when he accepts the Democratic presidential nomination on Aug. 28.

The only catch: You have to give some money to his campaign by July 31.

In the message, which features panoramic views of the 75,000-seat football stadium, Obama promises "an experience you'll never forget at what he calls "the biggest public event of this election so far."
