Information About The Survey
Sample Details
The late October survey findings in this report are based on two separate statewide surveys conducted among random samples of likely voters in California’s upcoming statewide special election. Interviewing for the first survey spanned the period October 18-24, 2005, while data collection for the second survey was completed October 25-30, 2005.
A total of 1,074 California adults were reached and screened by telephone in English and Spanish during the first survey, of whom 506 were considered likely voters in the statewide special election. For the second survey a total of 1,214 California adults were reached and screened in English and Spanish, of whom 581 were considered likely voters.
"... of whom 506 were considered likely voters..."
They don't provide the criteria for which the persons were deemed "likely voters" and I think this is where the fly is in the ointment.
