Methodology

Greenberg Quinlan Rosner Research, in conjunction with American Viewpoint, conducted this survey on behalf of the University of Southern California Dornsife College of Letters, Arts and Sciences and the Los Angeles Times.

These findings are based on a random sample survey of 1,537 (1,537 weighted) registered voters in the state of California, conducted from October 22 – 29, 2014.  Interviews were conducted by telephone using live interviewers from Interviewing Services of America.  Voters were randomly selected from a list of registered voters statewide and reached on a landline or cell phone depending on the number they designated on their voter registration.  Forty percent of this sample was reached on a cell phone.  Up to five attempts were made to reach and interview each randomly selected voter.  
 
The study includes an oversample of 400 known-Latino registered voters, with the total number of Latino voters interviewed at 519 (354 weighted).  All interviews among known Latinos were carried out via telephone by bilingual Latino interviewers, and conducted in the preferred language of the survey respondent, English or Spanish. Overall, 34 percent of interviews among the known Latino sample were conducted in Spanish and 66 percent in English. The technique of using fully bilingual interviewers yields higher response and cooperation rates and is greatly preferred because it does not terminate calls with Spanish-language households and require a callback.

The study also includes a subset of 1169 (1162 weighted) likely general election voters.  In this study, “likely voters” represent someone who has voted in at least one of the last two midterm general elections in California (2006 or 2010) and reports being “almost certain” to vote in Q.9; someone who has voted in both of the last two midterm elections (2006 and 2010) and reports that they are “almost certain” to vote or will “probably” vote in Q.9; someone who registered to vote after the 2010 election, voted in the 2012 election, and reports that they are “almost certain” to vote or will “probably” vote in Q.9; someone who registered after the 2012 election and reports that they are “almost certain” to vote or will “probably” vote in Q.9; or someone who reports having already voted in the 2014 election.

Upon completion of all interviewing, the results were weighted to bring the Latino oversample population into line with the racial and ethnic composition of registered voters in California. The data were weighted to reflect the total population of registered voters throughout the state, balancing on regional and demographic characteristics for gender, age, race, and party registration according to known census estimates and voter file projections.

The maximum sampling error for the overall sample of 1,537 registered voters is +/- 2.9 percentage points at the 95 percent confidence level.  The margin of error for subgroups is higher.  The margin of error for Latinos is +/- 4.9 percentage points at the 95 percent confidence level.  The margin of error for likely voters is +/- 3.3 percentage points at the 95 percent confidence level.
