Barack Obama has a 96% approval rating among Black Americans.
The approval rating for race relations is a sight lower than that. According to a CNN/Essence magazine poll, 55% of African Americans surveyed feel racial discrimination is a serious problem. During the 2008 election, that figure was at 38%.
From CNN:
The poll was conducted May 16-18, in telephone interviews with 505 African-Americans and 501 whites.
Blacks and whites had differing opinions of Obama’s performance:
-More than 60 percent of blacks felt that Obama met their expectations, while 46 percent of whites did.
-Thirty percent of blacks said Obama exceeded their expectations, compared with 16 percent of whites.
-Six percent of blacks said Obama did not meet expectations, compared with 35 percent of whites.
Both blacks and whites gave similar answers to a survey question about whether race relations will always be a problem in the United States.
-Forty-five percent of blacks answered yes, while 42 percent of whites said yes.
-Fifty percent of blacks said no, while 56 percent of whites said no.
The poll had a sampling error on these questions of plus or minus 4.5 percentage points
