The survey findings presented in this release are based on the results of interviews conducted September 15 - 22, 2014. The interviews were conducted at the Center for Opinion Research at Franklin & Marshall College under the direction of the poll’s Director Dr. G. Terry Madonna, Head Methodologist Berwood Yost, and Project Manager Jacqueline Redman. The data included in this release represent the responses of 520 Pennsylvania registered voters, including 245 self-identified Democrats, 212 self-identified Republicans, and 52 self-identified Independents. The sample of registered voters was obtained from Labels & Lists. Survey results were weighted (gender, region and party registration) using an iterative weighting algorithm to reflect the known distribution of those characteristics as reported by the Pennsylvania Department of State. The sample error for this survey is +/- 4.3 percentage points.
