Most Americans, 48 percent, back the jury's verdict of not guilty in George Zimmerman's trial in the death of Florida teen Trayvon Martin, according to one of the first extensive polls on the controversial case. Rasmussen Reports found that just 34 percent disagree with the verdict.

But the findings varied sharply along racial lines, with 68 percent of blacks in disagreement and 54 percent of whites agreeing that the jury made the right decision in the case.

Many blacks also told the pollster that they don't believe an all white jury, like the Zimmerman panel, can fairly decide a case involving a black man. But while 65 percent of blacks said that, 70 percent of whites said it is possible for an all-white jury to be fair in a case like Zimmerman's.

The poll also portrayed race relations as poor. "Just 30 percent of all Americans now rate race relations in the United States as good or excellent. Only 29 percent think those relations are getting better. But Americans consider blacks more likely to be racist than whites and Hispanics in this country," said the pollster.

The survey of 1,000 Adults was conducted on July 15-16, 2013 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence.
