2007 Castilian-Leonese regional election
A regional election was held in Castile and León on Sunday, 27 May 2007, to elect the 7th Cortes of Castile and León of the autonomous community. All 83 seats in the Cortes were up for election. It was held concurrently with regional elections in twelve other autonomous communities and local elections all throughout Spain.
Overview
Under the 1999 Statute of Autonomy, the Cortes of Castile and León were the unicameral legislature of the homonymous autonomous community, having legislative power in devolved matters, as well as the ability to vote confidence in or withdraw it from a regional president.Electoral system
Voting for the Cortes was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Castile and León and in full enjoyment of their political rights, provided that they were not sentenced—by a final court ruling—to deprivation of the right to vote, nor being legally incapacitated.The Cortes of Castile and León were entitled to three seats per each multi-member constituency—corresponding to the provinces of Ávila, Burgos, León, Palencia, Salamanca, Segovia, Soria, Valladolid and Zamora—plus one additional seat per each 45,000 inhabitants or fraction greater than 22,500. All members were elected using the D'Hondt method and a closed list proportional voting system, with an electoral threshold of three percent of valid votes being applied in each constituency. The use of the electoral method resulted in a higher effective threshold based on the district magnitude and the distribution of votes among candidacies.
As a result of the aforementioned allocation, each Cortes constituency was entitled the following seats:
| Seats | Constituencies |
| 15 | Valladolid |
| 14 | León |
| 11 | Burgos, Salamanca |
| 7 | Ávila, Palencia, Zamora |
| 6 | Segovia |
| 5 | Soria |
The law did not provide for by-elections to fill vacated seats; instead, any vacancies that occurred after the proclamation of candidates and into the legislative term were to be covered by the successive candidates in the list and, when required, by the designated substitutes.
Election date
The term of the Cortes of Castile and León expired four years after the date of their previous ordinary election, with election day being fixed for the fourth Sunday of May every four years. The election decree was required to be issued no later than the twenty-fifth day prior to the scheduled date of expiry of parliament and published on the following day in the Official Gazette of Castile and León. The previous election was held on 25 May 2003, setting the date for election day on the fourth Sunday of May four years later, which was 27 May 2007.The regional president had the prerogative to dissolve the Cortes of Castile and León and call a snap election, provided that no motion of no confidence was in process, no nationwide election was due and some time requirements were met: namely, that dissolution did not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor before one year had elapsed since a previous dissolution. In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the Cortes were to be automatically dissolved and a fresh election called, except if it happened in the final year before the expiry of the legislative term. Any snap election held as a result of these circumstances would not alter the period to the next ordinary election, with elected legislators merely serving out what remained of their original four-year term.
The election to the Cortes of Castile and León was officially called on 3 April 2007 with the publication of the corresponding decree in the BOCYL, setting election day for 27 May and scheduling for the chamber to reconvene on 19 June.
Outgoing parliament
The table below shows the composition of the parliamentary groups in the chamber at the time of the election call.Parties and candidates
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. Amendments to the electoral law in 2007 introduced requirements for a balanced composition of men and women 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:
Opinion polls
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.Voting intention estimates
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 the percentages in a smaller font; 42 seats were required for an absolute majority in the Cortes of Castile and León.Voting preferences
