The online news-voting site Digg has added a page tracking the Democratic and Republican candidates for president. Digg's a virtual unknown inside the Beltway, so the page's geek-skewed results aren't a true barometer of candidate popularity. They're more a gimmick by Digg founders Jay Adelson and Kevin Rose to guilt candidates into participating on their site. Predictably, the Internet's unlikely favorites lead: Barack Obama, Dennis Kucinich, and Mike Gravel on the Democratic side, Ron Paul and Mike Huckabee on the Republican side. You can view the candidates' favorite Digg stories — or rather, some anonymous campaign staffers' favorite stories. The lone holdout among candidates with a real shot at the nomination? Hillary Clinton. Her lack of participation shows she understands the true value of Web 2.0 in today's presidential election: none. An image of the current "Digg the President" leaders after the jump.
