Primary voters are using Facebook and Twitter to announce their support of a particular candidate or show off their "just voted" pride. The four remaining Republican candidates are doing their best to win over undecided voters via social media. And journalists covering the race to the White House are using social media to tell stories from the campaign trail.
Between the three states, 110 delegates are up for grabs. Will Mitt Romney grab most of them, further cementing his lead in the delegate count? Or will Rick Santorum do better in the deep south? What about Newt Gingrich and Ron Paul? And what are they all doing with their social media accounts and websites during the showdown?
