And you can listen to tonight's debate live on many NPR stations. We'll also have analysis and fact checking at NPR.org. Now, our next story looks not at the differences between the candidates, which we're sure to hear about tonight, but at a similarity. President Obama and Mitt Romney share something that goes to the core of this campaign. As NPR's Ari Shapiro reports, it comes up in every stump speech they give.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish. The stage is set in Denver for the first presidential debate tonight at 9:00 p.m. Eastern. The candidates are suiting up, reporters are gathering, live tweeters are sharpening their virtual pencils. And NPR's Mara Liasson is in Denver and she joins us for a preview. Welcome, Mara.
MARA LIASSON, BYLINE: Hi, Audie.
CORNISH: So what is the format for tonight's debate?
Fox News and other conservative media outlets claimed to have a scoop on Tuesday they called "Obama's other race speech." The tape that was supposed to turn this election around, however, was documented and reported on in 2007 by the very same news outlets.
