Updated: The conservative Civitas Institute released a poll Friday showing Republican Pat McCrory with a 16-point lead against rival Walter Dalton, though the sample appears skewed in McCrory's favor.
The poll shows McCrory getting 31 percent of the black vote, which strategists believe is unlikely.
Democrats could easily dismiss the poll -- taken during the Democratic convention -- but it mirrors an Elon poll last week showing McCrory with a 15-point edge. Dalton's campaign rejected the Elon poll as an outlier and a survey form the Democratic Public Policy Polling put the race at advantage-McCrory by 6 points.
Civitas released only a few poll questions and no numbers about the sample or methodology. The robo-poll was conducted Sept. 4-6 by contacting 500 registered voters. It's margin of error is 4.5 percent.
The survey also shows Paul Ryan with a better favorable rating than Joe Biden, his vice presidential counterpart. Ryan's favorable-unfavorable numbers were 48 to 38 percent; Biden's were 35 to 51 percent.
