A conservative group has questioned the Elon poll.
Tami Fitzgerald, an attorney with the conservative N.C. Family Policy Council, told the Associated Press that she disputed the methodology of the Elon University Poll which showed 50 percent of North Carolinians opposed a constitutional ban on gay marriage.
She argued that it surveyed all adults and not likely voters.
And she said the poll's question, which asked if the person would vote to "prevent any same-sex marriages," carried a negative tone that may have skewed the results.
"Phrasing it in a negative way probably elicited a stronger response in the negative," she said. Fitzgerald suggested asking if the person would approve an amendment defining marriage as a union between one man and one woman.
