And so, too, does the Republican Party that emerged from the Reagan era scarcely resemble the one that today selected Donald Trump as its standard bearer. As voting age population has grown increasingly non-white, older, and better educated, so too have the two major parties. Overall, more Americans say they are Democrats or Democratic-leaners (48%) than that they affiliate with the Republican Party or lean toward it (44%). Among those who identify as Democrats or say they lean toward the Democratic Party, 57% are white, down from 76% across Pew's surveys in 1992. Among Republicans and Republican-leaners, that change has been far less drastic, from 93% white in 1992 to 86% now.
