A few months back, I chided John Edwards's team for not effectively using its mobile text campaign. Then I softened my stance a little bit as they started using Twitter more effectively than their own text program, and now I truly believe that they have the entire mobile messaging strategy right.

For a while now, John Edwards held the lead of using Twitter to connect with voters. But Obama has finally gotten into the hang of it. And instead of simply answering the question, "What are you doing?" he's taking it even further and establishing a platform.

After reading a Wall Street Journal article entitled, "In '08 Race, Web Tactics Are Even More Integral, on March 19, Robbin Steif CEO of lunametrics wrote on the company's blog about the web analytics packages that the US presidential candidates and non-candidate were using.

Twitter became very popular the past couple of weeks, as all of the A-List bloggers, and folks attending SXSW in Austin started signing up and inviting all of their friends. Because of this, Twitter has proven itself as a great means by which candidates can make connections with potential voters.

Just a day after I posted about John Edwards texting campaign, a friend told me that Edwards was now using Twitter, a social networking tool that enables users to let friends and strangers know what they're doing.

Though the focus of techPresident is on how the candidates use the Web, as well as how voter-generated content affects the process, I've become very interested in what methods are being employed in the mobile space. One in particular wasn't very hard to find, it was in John Edwards YouTube video, "Tomorrow Begins Today," where he announces his candidacy and asks you to "Text Hope to 30644."

Ever since I first heard the announcement that John Edwards set up a campaign in Second Life, I've been very interested in finding out what the other candidates were doing there. I started with a search for Barack Obama and found that there were two groups in Second Life focusing on his campaign. The first is Obama for America, with 3 members, and the second is Obama for President, with 36 members.
