A new CNN poll of polls released Sunday suggests Senator Barack Obama, D-Illinois, has the support of 50 percent of likely Democratic primary voters in North Carolina, with 42 percent backing Senator Hillary Clinton, D-New York, and 8 percent still undecided.
This eight point Obama margin is down from a nine point lead Obama held in Saturday’s CNN poll of polls and down from his recent double digit lead in the state.
187 delegates are up for grabs when North Carolina and Indiana hold primaries on Tuesday.
The CNN poll of polls is an average of the latest surveys in the state.
