Non-Hispanic whites accounted for 89% of Republican self-identifiers nationwide in 2012, while accounting for 70% of independents and 60% of Democrats. Over one-fifth of Democrats (22%) were black, while 16% of independents were Hispanic.
These results are based on more than 338,000 interviews conducted as part of Gallup Daily tracking in 2012, and clearly underscore the distinct racial profiles of partisan groups in today's political landscape.
Republicans are overwhelmingly non-Hispanic white, at a level that is significantly higher than the self-identified white percentage of the national adult population. Just 2% of Republicans are black, and 6% are Hispanic.
Seventy percent of Americans who identify as independents are white, but independents have the highest representation of Hispanics (16%) of the three groups. Eight percent of independents are blacks.
Democrats remain a majority white party, but four in 10 Democrats are something other than non-Hispanic white. More than one in five Democrats are black, roughly twice the black representation in the adult population.
