Here is a good article about the future of politics on these social forums.
It goes on to say:
Daniel Gore and Jay Huerbin, both 18 and incoming University of Pittsburgh freshmen, have already joined or created such political groups.
Gore created a group supporting Santorum's Democratic opponent, Bob Casey Jr., on July 12. It has attracted members from New York University, Florida State University, Lehigh University, and the University of Pittsburgh.
"The aim is to generate... dialogue, to generate discussion. Too many people just ignore what's going on current-events- wise, and that's a problem, I think," said Gore, who is from Johnstown. "There's so many issues that... are debated in Congress, and I don't think our views about this should be ignored."
Huerbin, who lives in Gibsonia, a Pittsburgh suburb, joined a MySpace group about Swann to get more information about the Republican's candidacy while he decides whom to back for governor. Although Huerbin said MySpace and Facebook wouldn't be his only sources of information, they were definitely starting points.
"But if I come across something that I find interesting, I will Google it and look at it more in depth," Huerbin said.
A search of Facebook and MySpace sites shows at least four groups behind Gov. Rendell; nine for Swann; seven backing Santorum; and 14 promoting Casey. However, some of those sites simply advocate booting Rendell and Santorum from office.
In New Jersey, aides to U.S. Sen. Robert Menendez and his Republican challenger, State Sen. Tom Kean Jr., said office interns approached them about creating sites for them and the ideas were quickly accepted.
Scott Shields, director of Internet operations for the Menendez campaign, said the senator's two children were Facebook users and wanted to start a site as well. After only a few days on the Web, more than 300 supporters had joined the group, he reported.
