An average of 47% of Americans identified as Democrats or said they were independents who leaned Democratic in 2012, compared with 42% who identified as or leaned Republican. That re-establishes a Democratic edge in party affiliation after the two parties were essentially tied in 2010 and 2011.
The estimates are based on an aggregate of all 2012 Gallup and USA Today/Gallup polls, consisting of more than 20,000 interviews. [cont.]
