Way down the road, beyond the April 22 Primary in Pennsylvania with its 188 delegates, is North Carolina on May 6 with another 134 delegates at stake. A SurveyUSA poll conducted March 8-10 says Barack Obama leads Hillary Clinton 49 percent to 41 percent. The margin of error is 3.7 percent. This is only a small change from a month ago when Obama led by 10 points.
– **Age:** Obama has a big lead among voters under 49, a small one for voters 50-to-64 while Clinton, as she usually does, leads among those over 65 by almost 20 points. The over-65s make up 20 percent of the sample.
– **Race:** Clinton leads among white voters by 52 percent to 35 percent (61 percent of the sample) and Obama leads by 78 percent to 17 percent among black voters (32 percent of the sample). Hispanics only make up 4 percent of the sample and Clinton leads among that group.
