# 1991 Aragonese regional election

The 1991 Aragonese regional election was held on Sunday, 26 May 1991, to elect the 3rd Cortes of the autonomous community of Aragon. All 67 seats in the Cortes were up for election. The election was held simultaneously with regional elections in 12 other autonomous communities and local elections all throughout Spain.
The main loser in the election was the Democratic and Social Centre (CDS), which lost all of its 6 seats. The Aragonese Party (PAR) also lost two seats. The main gainers were the main two national parties, the Spanish Socialist Workers' Party (PSOE) and the newly created People's Party (PP). United Left also gained 1 seat.
The new legislature elected Emilio Eiroa of the PAR as the new President of Aragon by 34 votes to 33, after Hipólito Gómez de las Roces' refusal to reach a new agreement with the PP. All PAR and PP deputies supported Eiroa's election while the PSOE and IU deputies voted against. The tight arithmetic in the new legislature was further complicated in November 1992 when a PP deputy, Emilio Gomáriz, resigned from the PP, leaving him holding the balance of power between the PP-PAR bloc and the PSOE-IU bloc. In September 1993 the PSOE introduced a no-confidence motion against President Eiroa. In the subsequent vote Gomáriz appeared visibly nervous and claimed that he had received death threats against his children. He voted with the PSOE and IU deputies for Socialist José Marco as new President.

## Overview
### Electoral system

The Cortes of Aragon were the devolved, unicameral legislature of the autonomous community of Aragon, having legislative power in regional matters as defined by the Spanish Constitution and the Aragonese Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.
Voting for the Cortes was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Aragon and in full enjoyment of their political rights. The 67 members of the Cortes of Aragon were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency. Seats were allocated to constituencies, corresponding to the provinces of Huesca, Teruel and Zaragoza, with each being allocated an initial minimum of 13 seats and the remaining 28 being distributed in proportion to their populations (provided that the seat-to-population ratio in the most populated province did not exceed 2.75 times that of the least populated one).
In smaller constituencies, the use of the electoral method resulted in an effective threshold based on the district magnitude and the distribution of votes among candidacies.

### Election date

The term of the Cortes of Aragon expired four years after the date of their previous election. Legal amendments earlier in 1991 established that elections to the Cortes were to be fixed for the fourth Sunday of May every four years. The previous election was held on 10 June 1987, setting the election date for the Cortes on Sunday, 26 May 1991.
The Cortes of Aragon could not be dissolved before the date of expiry of parliament except in the event of an investiture process failing to elect a regional president within a two-month period from the first ballot. In such a case, the Cortes were to be automatically dissolved and a snap election called, with elected deputies merely serving out what remained of their four-year terms.

## Parties and candidates

The electoral law allowed for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition ahead of an election were required to inform the relevant Electoral Commission within ten days of the election call, whereas groupings of electors needed to secure the signature of at least one percent of the electorate in the constituencies for which they sought election, disallowing electors from signing for more than one list of candidates.
Below is a list of the main parties and electoral alliances which contested the election:

## Opinion polls

The table below lists voting intention estimates in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 34 seats were required for an absolute majority in the Cortes of Aragon.
