the 1952 presidential election, the American National Election Survey found that 6 percent of self-identified Democrats and 2 percent of self-identified Republicans were nonwhite. In 2012, the same survey found 43 percent of self-identified Democrats, but only 9 percent of self-identified Republicans, were nonwhite.19 So not only was the 2012 electorate far, far more racially diverse than the 1952 electorate, but that diversity was concentrated in the Democratic Party.
