Amid the congratulations and the angry posts from Romney supporters were some praising the photo. "They are an absolutely gorgeous couple!!! So in love!" said one comment. The posts reaffirmed the pre-eminence of social media as a crucial communications platform in the 2012 presidential race. Obama's campaign acknowledged his victory on Twitter and Facebook before he e-mailed supporters or addressed a victory rally early Wednesday in Chicago. The messages also rode a massive wave of Twitter chatter about the election returns. Twitter saw 31 million tweets on Election Day, and hit a peak of 327,452 tweets per minute as Obama was declared the winner. The Obama campaign has not revealed who took the photo, although it is nearly identical to ones snapped by Jim Watson, who covered the campaign event for Agence France-Presse. if(typeof CNN.expElements==='object'){CNN.expElements.init();}
