Methodology
This survey of 500 registered California voters was conducted between February 26 and February 29, 2020, and is based on live telephone interviews of adults who indicated that they plan to vote in the March 3, 2020 Democratic Presidential primary. Each area’s quota and demographic information -- including race and age -- was determined from exit polling data as well as American Community Survey Census data. Samples of both standard landlines and cell phones were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportional to the number of likely voters expected based on similar past elections. The 57 California counties were grouped into five general regions. Respondents in the household were selected by initially asking for the youngest adult. The margin of sampling error for results based on the total sample is +/- 4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.

This survey of 500 young Iowa residents was conducted between January 15 and January 20, 2020, and is based on live telephone interviews of adults who indicated they were residents of Iowa. Each area’s quota and demographic information -- including geography and race -- was determined from 2010 Census data, the 2018 American Community Survey, and the Iowa State Data Center. Samples of both standard landline and cell phones were called using a probability-proportionate-to-size method, which means that the age-specific listed phone numbers assigned to each county were proportional to the number of residents between the ages of 18-29 years. The 99 Iowa counties were grouped into five general regions. Respondents in the household were selected by initially asking for the youngest adult. The margin of sampling error for results based on the total sample is +/-4.4 percentage points. The margin of sampling error for 150 potential Democratic Caucus-goers is +/- 8.0 percentage points. The margin of sampling error for 154 potential Republican Caucus-goers is +/- 7.9 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows.

Iowa's 99 counties were grouped into five general regions. The margin of sampling error for results based on the total sample is plus or minus 4.4 percentage points.
