The Baltimore Sun telephone survey of 798 likely voters was conducted Oct. 15-20. The Sun's pollster, OpinionWorks of Annapolis, used a Maryland Board of Elections database to identify registered voters with a history of voting in gubernatorial elections or who had registered to vote since the last election, and obtained survey results from those who ranked themselves seven or higher on 1 to 10 scale of their likelihood to vote. The Sun's sample was designed to approximate the racial, gender, geographic, partisan and age breakdown of the state's voting population as a whole, based on turnout patterns averaged over the last four Maryland general elections. Results were weighted to reflect a higher-than-average Republican turnout this year, and slightly lower African American participation than in recent elections. The margin of error for questions that reflect the entire sample is 3.5 percentage points, which means that in 95 times out of 100, the actual answer obtained by surveying every Maryland voter would be within 3.5 percentage points of the answer obtained by using the sample. For questions about Anne Arundel voters and slots, the sample size was 422 voters, with an error rate of 4.8 percentage points.
