Not so with another ad that also began this week. It's called "The Politics of Parsing" and takes direct aim at New York Sen. Hillary Clinton. It airs solely on YouTube.
The second ad splices pictures of Clinton from Tuesday's debate in Philadelphia giving seemingly contradictory answers to questions about Iraq, Social Security and immigration. To underscore the point, the "Blue Danube" waltz plays in the background.
Like other candidates, Edwards has used YouTube videos before to showcase an ad. But this is the first one that's offered direct criticism of a Democratic rival. It continues a drumbeat he began even during the debate of accusing Clinton of "double-talk."
Edwards' ad is a response to one Clinton's campaign posted YouTube ad after the debate. It's called "The Politics of Pile On."
"Four years ago, John Edwards told voters that if they wanted someone to attack other Democrats, he wasn't their guy," Clinton spokesman Mo Elleithee said Saturday. "As his poll numbers continue to slip, he's unfortunately become that guy."
As of Saturday, Edwards' video had already been viewed more than 143,000 times. That's not bad reach for an ad that's essentially free to produce and post.
"Those aren't 143,000 people in Iowa or New Hampshire," says Andrew Taylor, a political scientist at N.C. State. "But it's still a pretty cost-effective way of getting a message across."
Edwards' spokeswoman Colleen Murray said YouTube offers "an innovative and immediate way to communicate our message."
"In this case, it immediately showed voters that this wasn't about the 'politics of pile-on,'" she said. "It was about Senator Clinton practicing the 'politics of parsing.'"
