Methodology: The study of 600 registered voters was conducted June 11-13 by Tel Opinion Research of Alexandria, Virginia. All respondents were part of a fully representative sample of registered voters in North Carolina. For purposes of this study, respondents interviewed voted in either the 2002, 2004 or 2006 general election or were newly registered voters since 2006. The voters were interviewed using live callers.
The confidence interval associated with a sample of this size is such that: 95% of the time, results from 600 interviews (registered voters) will be within +- 4% of the “True Values.” “True Values” refer to the results obtained if it were possible to interview every person in North Carolina who had voted in either the 2002, 2004 or 2006 general elections or were newly registered voters since 2006.
