Civil Beat surveyed a random sample of 869 registered voters on June 18-20 and June 24, using interactive voice response technology (touch-tone polling). Calls were made to landline and cell phones. Cell phones were contacted in compliance with federal law.

Results were balanced for age, gender, race/ethnicity, and phone type. The sampling margin of error for the full sample is +/- 3.3 percentage points. The margin of error indicates that in 95 percent of samples of this size, the results will be within +/- 3.3 percent of the actual percentage in the full population of registered voters. Other sources of error, such as imperfect response rates, are also common in public opinion research and may affect the results. The margin of error for any crosstabulated result is larger than the margin of error of the corresponding topline result.

The poll was conducted by Civil Beat working with Merriman River Group, a full-service consulting organization specializing in opinion research, election management, and communications.
