Social networking has become a prominent element on both candidates’ campaigns. In the early primary season in 2007, PEJ found that 16 of the 19 candidate Web sites linked to or otherwise utilized MySpace or Facebook. And, in claiming the Democratic nomination, Obama announced that social networking was a major key to his success. 
In the general election battle, Obama’s campaign has remained deeply active in the social networking world and has maintained dominance over McCain. Coming out of the Republican Convention, McCain has stepped up his presence in the social networking world, but there is still a long gap.
McCain’s Web site does not link to any social networking sites on its home page but maintains a presence on six: MySpace, Facebook, YouTube, Digg, Flickr and—added in September—LinkedIn. But is it up to supporters to find these pages on their own. The McCain Web site also recently added a tool that allows members of 27 different social networking sites to quickly forward Web content—text, photos, and video—to fellow social networkers.
In addition, unofficial, user-created groups that support for McCain exist on three other networking sites: BlackPlanet, targeted at the African American community, Faithbase, a Christian social networking site and Eons, which calls itself the online community for (baby) boomers.
MySpace and Facebook
A close look at listed MySpace “friends” and Facebook supporters on the popular social networking sites reveals the tremendous advantage established by Obama, despite recent steps by the McCain campaign at gaining ground.
As of early September, Obama has more than a 5-to-1 lead over McCain in number of friends. This is down from a 7-to-1 advantage a month earlier.
A larger social networking base gives the Obama campaign a more sizeable built-in audience of supporters for direct updates and appeals.
Barackobama.com adds one other social networking tool, a complement to the campaign-sponsored Web site fightthesmears.com, which was conceived to dispel misleading assertions about the candidate.  The official campaign site enlists supporters as fact-checkers, to dispel false assertions—once exclusively the domain of the press and campaigns.
Similar to the lopsided social networking campaign, McCain’s official YouTube channel as of August had fewer than a quarter as many videos as Obama’s. The Obama channel also had about five times as many subscribers, and most telling, more users have visited Obama’s YouTube channel page, by a staggering 11-to-1 margin.
Through a series of video ads painting Obama as an inexperienced “celebrity,” McCain gained some ground on Obama in recent weeks, though it made little real dent in the Obama lead.
After the McCain campaign posted the videos “Celebrity,” and “The One,” which mocked the press and Obama, McCain’s YouTube channel outpaced Obama’s for seven straight days.  Since then, the numbers of new subscribers and videos watched on the McCain YouTube channel have grown at a higher rate than on the Obama channel. That has narrowed the gap of videos seen each day, however, only slightly.
But by all indications, Obama continues to be more prominent on YouTube. In absolute terms—number of channel visitors, new subscribers, videos watched and new videos posted—he continues to far outpace McCain.
