Esta es una lista de las encuestas de opinión pública en todo el estado que se han realizado en relación con las primarias demócratas para las elecciones presidenciales de los Estados Unidos de 2020 . Las personas nombradas en las urnas son candidatas declaradas o han recibido especulaciones mediáticas sobre su posible candidatura.

Dado el gran número de candidatos potenciales, las puntuaciones de ciertos candidatos con pocas votaciones y con poca frecuencia se han combinado dentro de la columna "otros"; sus puntajes exactos pueden verse en las notas al pie asociadas con cada encuesta. Las encuestas incluidas son entre demócratas o demócratas e independientes de tendencia demócrata, y no incluyen a independientes de tendencia republicana. Las elecciones estatales se ordenan en la fecha programada para las primarias o el caucus del estado. Las encuestas abiertas se incluyen y se marcan con un asterisco (*), pero las versiones cerradas de dichas encuestas se enumeran cuando es posible. Si se proporcionan varias versiones de las encuestas, se prioriza la versión utilizada para la calificación del debate, luego la versión entre los votantes probables, luego los votantes registrados y luego los adultos.

  Joe Biden

  Bernie Sanders

  Michael Bloomberg

Si más de 20 candidatos alcanzan cualquiera de los umbrales, los candidatos que alcancen ambos umbrales recibirán la máxima prioridad para participar en los debates, seguidos de los que tengan el promedio de votación más alto y los que tengan más donantes. Los encuestadores y patrocinadores de las encuestas designados para su consideración por el DNC son Associated Press , ABC News , CBS News ,CNN , The Des Moines Register , Fox News , Las Vegas Review-Journal , Monmouth University , NBC News , The New York Times , National Public Radio , Quinnipiac University , Reuters , University of New Hampshire , USA Today , The Wall Street Journal , The Washington Post y la Universidad de Winthrop . ^[1] Las encuestas abiertas no cuentan para el umbral de votación. ^[2]

Sin fecha aún establecida se basan en fechas estimadas por The Green Papers.basado en años pasados. Los números de delegados comprometidos que se enumeran a continuación se basan en los votos presidenciales en 2008, 2012 y 2016, así como en el número de votos electorales de cada estado en 2020. El número de miembros del DNC y líderes de partidos distinguidos en el recuento de PLEO no comprometidos ( líderes de partido y funcionarios electos) delegados se basa en la Convención Nacional Demócrata de 2016, mientras que el número de funcionarios no comprometidos (gobernadores, miembros del Congreso y sus equivalentes en jurisdicciones no estatales) refleja su total actual. El número de delegados comprometidos aún no tiene en cuenta las bonificaciones de delegado o las penalizaciones por tiempo o agrupación. ^{[16] [17] [18]}

Los estados enumerados con un fondo lavanda y un asterisco (*) aún no tienen una fecha establecida por el estatuto existente. Los estados con un fondo amarillo claro y una daga (†) están configurados para cambiar la fecha de las primarias o del caucus luego de la aprobación esperada de la legislación que mueva las fechas de sus concursos. Si aún no figura como tal, la fecha a la que se espera que se traslade el concurso se incluye entre paréntesis.

Los resultados de una encuesta final de The Des Moines Register no se dieron a conocer como estaba programado el 1 de febrero, luego de que un entrevistado se quejara de que Pete Buttigieg no fue dado como una opción de encuesta durante su entrevista, y la omisión supuestamente atribuida a un error humano . Como la empresa de encuestas no pudo determinar si el error fue un incidente aislado o no, la encuestadora Ann Selzer decidió retener los resultados de la encuesta por completo, marcando la primera vez en 76 años que la encuesta final previa al caucus no fue publicada por el Regístrese . ^{[19] [20]} La encuesta se filtró más tarde en Twitter , con los resultados confirmados por FiveThirtyEight.mostrando a Sanders a la cabeza con un 22%, seguido de Warren con un 18%, Buttigieg con un 16% y Biden con un 13%. ^[21]
