(CNN) - White voters continue to support the Republican presidential candidate, as they have for many years. In the exit polls reported thus far tonight, 53 percent of whites say they voted for McCain while 43 percent of whites voted for Obama.
Obama, however, has a dramatic edge among African-Americans (96 percent), Latinos (67 percent ) and Asians (63 percent). Significantly, America's non-white vote is increasing as a proportion of the entire electorate. In the 1992 presidential election, whites made up 87 percent of all voters. This proportion fell to 83 percent in 1996; to 81 percent in 2000 and 77 percent in 2004. So far in today's exit polling, whites make up 75 percent of the electorate. Projected demographic trends indicate that the proportion of non-white voters, particularly Hispanics, will increase further in the future.
Exit polling also shows that McCain winning among Southern whites by a margin of 69 percent to 31 percent. Outside the South, McCain won among white voters 51 percent to 49 percent.
