About this Poll
The findings in this report are based on a Field Poll completed August 14-28, 2014 among 467 voters considered likely to vote in the November 2014 general election. Interviews were administered by telephone using live interviewers in six languages and dialects – English, Spanish, Cantonese, Mandarin, Korean, and Vietnamese. In order to cover a broad range of issues and still minimize respondent fatigue, the image ratings of the gubernatorial candidates were asked of a random subsample of 236 likely voters

Sampling error estimates applicable to the results of any probability-based survey depend on sample size and the percentage distributions being examined. The maximum sampling error for results from the overall likely voter sample is +/- 4.8 percentage points, while findings based on the random subsample of likely voters have a maximum sampling error of +/- 6.5 percentage points. The maximum sampling error estimates are based on survey findings in the middle of the sampling distribution (i.e., results at or near 50%). Percentages at either tail of the distributions (i.e., results closer to 10% or 90%) have somewhat smaller margins of error. There are other potential sources of error in surveys of public opinion besides sampling error. However, the overall design and execution of this survey sought to minimize these other possible errors.
