DENVER (CNN) – The McCain campaign has suggested Sen. Barack Obama is little more than a substance-less celebrity. The size of the crowd gathered to watch Obama formally accept his party’s nomination may do little to dispel that line of attack.
“They will have more than 85,000 people, perhaps more than 90,000 people, in this stadium by the time Barack Obama speaks,” Chief National Correspondent John King said Thursday evening. “There is a concern that the Obama campaign may have issued as many as 20,000 more tickets for this event” than the stadium can hold.
Local authorities are working with the Secret Service to get as many people into the stadium as possible. But there is a concern that several thousand people could be turned away.
In addition to the tens of thousands present in Invesco Field, millions of Americans across the country will be watching Obama on television and online.
