Keystone Poll, May 2007

Methodology

Survey results are based on the results of interviews conducted between May 2 and 7, 2007 with 385 registered Democrats. The interviews were conducted at the Center for Opinion Research at Franklin & Marshall College under the direction of the Poll’s Director, G. Terry Madonna, the Poll’s Head Methodologist, Berwood Yost, and the Poll’s Project Manager Jennifer Harding. Telephone numbers for the survey were generated via random digit dialing, and respondents were randomly selected from within each household. The sample error is +/- 5.0 for the total sample.
