Partisan Polarization Surges in Bush, Obama Years 1987-2012


Partisan Polarization Surges in Bush, Obama Years 


Trends in American Values: 1987-2012

SECTION 9: TRENDS IN PARTY AFFILIATION

The number of political independents has continued to grow, as both parties have lost ground among the public. Based on surveys conducted this year, 38% describe themselves as independents, up from 32% in 2008 and 30% in 2004.
The proportion of independents is now higher than at any point in more than two decades. Looking back even further, independents are more numerous than at any point in the last 70 years. (For trends in party identification from 1939-2012, seethis interactive feature.)
Meanwhile, the percentage of self-described Democrats has fallen from 36% four years ago to 32% today. Republican identification has remained largely stable over this period (24% today, 25% in 2008). In 1991, however, there were nearly equal percentages of Republicans (31%), Democrats (31%) and independents (33%).
The Democrats continue to hold an advantage in leaned party identification: In 2012 surveys, 48% either affiliate with the Democratic Party or lean Democratic while 40% either identify as Republicans or lean toward the GOP. That is little changed from recent years, but in 2008 the Democrats held a 15-point lead in leaned party affiliation (51% to 36%).
