Gallup reports:
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.
Without leaners, however, the picture is different: 40%
independent, 31% D, 28% R.
Americans last year continued their trend toward greater political independence. The 40% who initially identified as political independents matched the record high from 2011. That is particularly notable, given that the usual pattern is for the percentage of Americans identifying as independents to decline in a presidential election year. In each of the last four presidential election years, dating back to 1996, the percentage of independents was lower than in the year prior to the election.
