About this Poll
Interviewing for The Roanoke College Poll was conducted by The Institute for Policy and Opinion Research at Roanoke College in Salem, Va. between October 29 and November 2, 2017. A total of 781 likely voters in Virginia were interviewed. Telephone interviews were conducted in English and Spanish. The sample was drawn from a list of registered voters compiled by L2 Political. Participants were sampled from that list, which has phone numbers associated with approximately 60 percent of the registered voters in Virginia. The list included both landlines and cell phones. Cell phones constituted 39 percent of the completed interviews.

Questions answered by the entire sample of 781 residents are subject to a sampling error of plus or minus approximately 3.5 percent at the 95 percent level of confidence. This means that in 95 out of 100 samples like the one used here, the results obtained should be no more than 3.5 percentage points above or below the figure that would be obtained by interviewing all Virginia likely voters who have a home telephone or a cell phone. Where the results of subgroups are reported, the sampling error is higher.
