ABC News’ David Chalian and Teddy Davis report:
When Sen. Barack Obama, D-Ill., moves the Democratic National Convention from the Pepsi Center to Invesco Field in Denver on Thursday, the freshman senator is planning to speak from a columned stage resembling an ancient Greek temple.
"Is this from the Onion?" quipped a McCain adviser.
The reference to the satirical newspaper came after Reuters reported that Obama is planning an elaborate rock concert setup complete with post-speech fireworks.
The national anthem will even have a touch of celebrity: Jennifer Hudson, the Oscar-winning actress and former "American Idol" castoff, will perform the honors at the onset of the evening.
Starting with a July ad which included footage of Paris Hilton and Britney Spears, the McCain campaign has been airing a series of television ads which paint Obama as a celebrity lacking in substance.
The celebrity-like trappings of Obama’s Thursday’s speech may have given the Republicans new ammo.
