These results are based on telephone interviews with a randomly selected national sample of 897 registered voters, aged 18 and older, conducted Nov. 11-14, 2007. For results based on this sample, one can say with 95% confidence that the maximum error attributable to sampling and other random effects is ±4 percentage points. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
