Opinion polling for the Spanish general election, 1986

In the run up to the Spanish general election of 1986, various organisations carried out opinion polling to gauge voting intention in Spain. Results of such polls are displayed in this article.

The date range for these opinion polls are from the previous general election, held on 28 October 1982, to the day the next election was held, on 22 June 1986.

Vote estimations

Poll results are listed in the table 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 leading party's colour. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty.
