Poll results are listed in the tables below in reverse chronological order, showing the most recent first, and using the date the survey's fieldwork was done, as opposed to the date of publication. If such date is unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the candidate's colour. In the instance of a tie, the figures with the highest percentages are shaded. Polls show data gathered among Cs voters/supporters as well as Spanish voters as a whole, but not among party members, who are the ones ultimately entitled to vote in the primary election.
