Poll Demographics

About this Poll

For this Temple Poll a randomly selected sample of Pennsylvanians registered to vote were interviewed by telephone between March 27 and April 9, 2008. Once the interviewing was complete, the data were weighted to correct for unequal probabilities of selection and response, and to ensure that the demographic characteristics of the sample match the population of registered voters in Pennsylvania. The sample included 583 likely voters, identified on the basis of their voting history and engagement with the campaign. With a sample of this size, the overall margin of error attributable to sampling is 4 percentage points. The sampling error for subgroups is larger.
