A regional election was held in Aragon on 26 May 2019 to elect the 10th of the autonomous community. All 67 seats in the were up for election. It was held concurrently with regional elections in eleven other autonomous communities and local elections all across Spain, as well as the 2019 European Parliament election.
The election resulted in the most fragmented parliament to date, with up to eight parliamentary groups being formed. The Spanish Socialist Workers' Party (PSOE) of regional president Javier Lambán emerged as the largest political party and was able to retain government throughout a diverse coalition agreement including Podemos, the Aragonese Party (PAR) and the Aragonese Union (CHA). The People's Party (PP) obtained the worst result in its history, whereas Citizens (Cs) emerged with a strong third-place position. The far-right, represented by Vox, entered parliament for the first time.
Under the 2007 Statute of Autonomy, the Cortes of Aragon were the unicameral legislature of the homonymous autonomous community, having legislative power in devolved matters, as well as the ability to grant or withdraw confidence from a regional president.
Voting for the was based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in Aragon and with full political rights, provided that they had not been deprived of the right to vote by a final court ruling. Additionally, non-resident citizens were required to apply for voting, a system known as "begged" voting ().
The of Aragon had a minimum of 65 and a maximum of 80 seats, with the electoral law fixing its size at 67. All were elected in three multi-member constituenciesâÂÂcorresponding to the provinces of Huesca, Teruel and Zaragoza, each of which was assigned an initial minimum of 13 seats and the remaining 28 distributed in proportion to population (with the seat-to-population ratio in the most populated province not exceeding 2.75 times that of the least populated one)âÂÂusing the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) in each constituency. The use of this electoral method resulted in a higher effective threshold depending on district magnitude and vote distribution.
As a result of the aforementioned allocation, each constituency was entitled the following seats:
The law did not provide for by-elections to fill vacant seats; instead, any vacancies arising after the proclamation of candidates and during the legislative term were filled by the next candidates on the party lists or, when required, by designated substitutes.
The term of the of Aragon expired four years after the date of their previous election, unless they were dissolved earlier. The election decree was required to be issued no later than the twenty-fifth day prior to the scheduled expiration date of parliament and published on the following day in the Official Gazette of Aragon (BOA), with election day taking place on the fifty-fourth day from publication. The previous election was held on 24 May 2015, which meant that the chamber's term would have expired on 24 May 2019. The election decree was required to be published in the BOA no later than 30 April 2019, with the election taking place on the fifty-fourth day from publication, setting the latest possible date for election day on 23 June 2019.
The regional president had the prerogative to dissolve the of Aragon at any given time and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year after a previous one. In the event of an investiture process failing to elect a regional president within a two-month period from the 's reconvening, the chamber was to be automatically dissolved and a fresh election called.
The of Aragon were officially dissolved on 2 April 2019 with the publication of the corresponding decree in the BOA, setting election day for 26 May and scheduling for the chamber to reconvene on 20 June.
The table below shows the composition of the parliamentary groups in the chamber at the time of dissolution.
The electoral law allowed for parties and federations registered in the interior ministry, alliances and groupings of electors to present lists of candidates. Parties and federations intending to form an alliance 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. Additionally, a balanced composition of men and women was required in the electoral lists, so that candidates of either sex made up at least 40 percent of the total composition.
Below is a list of the main parties and electoral alliances which contested the election:
The tables below list opinion polling results 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.
The table below lists weighted voting intention estimates. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. 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.
The table below lists raw, unweighted voting preferences.
