Filtering: 800 registered voters with home telephones in Virginia’s 9th Congressional District were interviewed by SurveyUSA 10/21/10 through 10/25/10, using Registration Based Sample (RBS) from Aristotle in Washington DC. Of the registered voters, 608 were determined by SurveyUSA to have already voted, or to be likely to vote on or before election day 11/02/10.
****************************************************************
RV poll...a LV model would probably trend more to Griffith.
Not completely RV...75% filtered for LV or already voted.
