Field dates: October 2-8, 2012
Sample: 500 registered Massachusetts voters
The survey was conducted by YouGov America (http://yougov.com). YouGov interviewed 573
respondents who were then matched down to a sample of 500 to produce the final dataset. The
respondents were matched on gender, age, race, education, party identification, ideology, and political
interest. YouGov then weighted the matched set of survey respondents to known marginals for
registered voters from the state of Massachussetts from the American Community Survey. All analyses
were produced using these weights.
The margin of error for analyses of Massachusetts adults is 5%. The margin of error for registered
voters is 5.4%. The margin of error would be larger for subpopulations.
