President Obama announced his 2012 re-election bid on Monday, and much like the 2008 election, social-networking tools are front and center.
Obama's campaign Web site, barackobama.com, encourages supporters to "Get In with Facebook." Using Facebook Connect, users can pledge their support via their Facebook Wall, and encourage friends to do the same. Obama's Facebook page has about 19 million fans.
Supporters can also say they're "in" via Twitter or email.
In a Monday email, Obama said he is "focused on the job you elected me to do, and the race may not reach full speed for a year or more, [but] the work of laying the foundation for our campaign must start today."
"In the coming days, supporters like you will begin forging a new organization that we'll build together in cities and towns across the country," he continued. "And I'll need you to help shape our plan as we create a campaign that's farther reaching, more focused, and more innovative than anything we've built before."
Obama's 2008 election focused heavily on social networking, leveraging the power of Facebook and Twitter to get the word out. Opponent John McCain, meanwhile, got some heat for admitting he was not the most tech-savvy person, and running what Democrats called a "dial-up campaign."
No Republicans have formally entered the race against Obama, though potential candidates include Mitt Romney, Mike Huckabee, Newt Gingrich, Sarah Palin, Tim Pawlenty, and Michelle Bachmann, among others.
