Sampling method: Respondents were initially selected on September 7-14 from YouGov’s panel using sample matching. A random sample (stratified by age, gender, race, education, and region) was selected from the 2005–2007 American Community Study. Voter registration, turnout, religion, news interest, minor party identification, and non-placement on an ideology scale, were imputed from the 2008 Current Population Survey Registration and Voting supplement and the Pew Religion in American Life Survey. Matching respondents were selected from the YouGov panel, an opt-in Internet panel.

Respondents were recontacted on October 4-11 for the second wave of the YouGov poll. The percentage of likely voters who were successfully recontacted was 87.2%.

Weighting: The sample was weighted using propensity scores based on age, gender, race, education, news interest, voter registration, and non-placement on an ideology scale.

Number of respondents: 1169 likely voters.

Margin of error ± 3.5% (adjusted for weighting).
