WASHINGTON  - US President Obama’s campaign team is proving again in 2012 to be more conscious than rival Republicans are of the power of the Internet, particularly Twitter, a study said. With online communications set to be even more important than in 2008, when Obama raised the bar on targeting voters and donors via the Internet, the Pew Research Center said he is dominating the 2012 digital campaign stakes. While Mitt Romney’s team averaged one tweet per day, Obama averaged 29 tweets - 17 on @BarackObama (the Twitter account associated with his presidency) and 12 on @Obama2012 (the account associated with his campaign), during the research study period.
