Joe Biden has a comfortable lead over Bernie Sanders in the Arizona primary and, if he is the Democratic nominee, he would beat Donald Trump in the state by a margin of 50% to 42% , according to a poll of registered voters conducted by Univision News and the Arizona State University’s Center for Latina/os and American Politics .

Methodology: Univision News partnered with Arizona State University’s Center for Latina/os and American Politics Research School of Transborder Studies to commission a statewide poll of Arizona registered voters with an oversample of Arizona Latinos. The poll was implemented from March 6 – 11, 2020. The statewide portion (N=1,036) contains a margin of error of +/- 3.0 and the Latino portion (n=502) contains a margin of error of +/-4.4. Democratic primary vote choice was asked of 541 respondents statewide and carries a margin of error of +/- 4.2 and, and 305 Latino Democratic voters, +/- 5.6. Surveys were administered in English or Spanish at the discretion of the respondent and included a mix of cell phone, landline telephone and online self-completed interviews. All respondents are confirmed to be registered to vote. Respondents were randomly selected from the voter file and invitations for interviews were done by live caller, email, or text message. Invitations were bilingual at point of contact and allowed respondent to complete the interview in their language of choice. After data collection was complete a post-stratification weight was added to balance the data to the best known Census ACS data on the eligible voting population in Arizona. The survey was overseen by Dr. Sergio Garcia-Rios, director of polling for Univision, and administered by Latino Decisions.
