The 2008 Collaborative Multi-racial Post-election Survey (CMPS) is a national telephone survey of registered voters, with comparably large samples of African Americans, Asian Americans, Latinos, and Whites. The telephone survey, conducted between November 9, 2008 and January 5, 2009, is the first multiracial and multilingual survey of registered voters across multiple states and regions in a presidential election. In contrast to the 2008 American National Election Study (ANES) which oversampled Black and Latino voters, and was available in Spanish, the CMPS was available in six languages and contains robust samples of the four largest racial/ethnic groups: Whites, Latinos, Blacks, Asians. The CMPS contains 4,563 respondents who registered to vote in the November 2008 election and who self-identified as Asian, Black, Latino, and White. The survey was available in English, Spanish, Mandarin, Cantonese, Korean, Vietnamese and respondents were offered the opportunity to interview in their language of choice. The six states that were sampled to produced robust samples of all four major racial groups include California, Texas, New York, Florida, Illinois, and New Jersey, and the statewide samples range from 243 to 669 cases. In order to arrive at more nationally representative samples of each minority group, the study added two supplemental states per racial group, including Arizona and New Mexico (Latinos), North Carolina and Georgia (Blacks), Hawaii and Washington (Asians). Of these 12 states, 3 were considered political battlegrounds in the 2008 Presidential electorate — New Mexico, Florida, and North Carolina. In order to examine multi-racial politics in competitive and non-competitive environments, the study supplemented the sample with six additional diverse battleground states: Colorado, Michigan, Nevada, Ohio, Pennsylvania, and Virginia. As of the 2008 election, two-thirds of the national electorate was concentrated in these 18 states. For Latinos, 92 percent of all registered voters reside in these states; 87 percent of Asian Americans; and 66 percent of Blacks, and 61 percent of Whites. The November 2008 CMPS provides estimates of the registered voter population by race, age, gender, and education level which was applied to the sample, by racial group, so that the distributions match those of the Census on these important demographic categories. In the study, there are 51 items dealing with sociopolitical attitudes, mobilization and political activity. Additionally, there are 21 items that capture demographic information, including: age, ancestry, birthplace, education, ethnicity, marital status, number in the household, religiosity, gender, media usage and residential context.

2012. Collaborative Multi-racial Post-Election Study (CMPS). Co-Principal Investigator with Ange-Marie Hancock, Jillian Anne Medeiros, and Gabe Sanchez, Ali Valenzuela. A national, multiracial and multilingual survey of registered voters in the 2012 presidential election, N=2,616.

The CMPS 2012 is comprised of 2,616 registered voters who self-identified as Black (n=804), Latino (n=934), or White (n=878). The GfK Group (GfK, formerly Knowledge Networks) conducted the survey. Pretests of the survey were conducted between November 8, 2012 and November 19, 2012 in both English and Spanish. A STATA dataset containing the pretest interviews was reviewed prior to the main sample launch. Because changes were made to the main survey as a result of the pretest, the pretest interviews were not included as part of the main survey dataset. The main survey was conducted between November 16, 2012 and November 26, 2012 in both English and Spanish. The survey examined individual’s experiences voting and attitudes about social and economic issues prominent in the 2012 election. The CMPS uses probability-based web panels designed to be representative of the United States instead of “opt-in” panels that include only individuals with Internet access who volunteer themselves for research. As a result, panel members come from listed and unlisted telephone numbers, telephone and non-telephone households, and cell phone only households, as well as households with and without Internet access, which creates a representative sample. Panel members are recruited through national random samples (both by telephone and mail). Households are provided with access to the Internet and a netbook computer, if needed. Otherwise, participants are rewarded with incentive points that are redeemable for cash. In an effort increase completion of the surveys, panel members can enter special raffles or can be entered into special sweepstakes with both cash rewards and other prizes to be won. The median completion time of the survey was 20 minutes and the completion rate was 56.3%. Respondents were considered qualified if they did not refuse more than 4 of the first 7 questions in the survey. Those who refused 4 or more of the first 7 questions were terminated from the survey. The qualification rate was 99.8%. To reduce the effects of any non-response and non-coverage bias in the overall panel membership, a post-stratification adjustment was applied based on demographic distributions from the most recent data from the Current Population Survey (CPS). An additional Spanish language adjustment was used based on the 2010 Pew Hispanic Center Survey (the most recent available published data at the time). Language usage adjustments allow for the correct proportional fitting of Spanish-speaking members relative to other English-speaking Hispanic and non-Hispanic panel members within Census regions. The CMPS includes 37 items dealing with sociopolitical attitudes, mobilization political activity, advertising exposure and neighborhood context as well as three embedded survey experiments. Additionally, there are 15 items that capture demographic information, including: age, ancestry, birthplace, education, ethnicity, Latin American racial descriptors, skin color, marital status, number in the household, religiosity, gender, sexual orientation, internet usage and residential context. In addition to the survey and demographic data, the 2012 CMPS also includes latitude and longitude values for each respondent. This allows for more nuanced modeling with regard to contextual variables at the tract, city, county, MSA Level, and Congressional district.
