First term (2006–2010) 2005 general election Significant social conflicts at the turn of the twentieth century fostered a change in political action in Santa Cruz. Emulating the tactic of
mass mobilization utilized by the country's
indigenous and
unionist sectors to achieve their goals, Cruceños took to the streets demanding
expanded departmental autonomy. By 2004, Ortiz's early support for the decentralization process had led him to gain regional notoriety. When Quiroga contested the presidency in 2005, Ortiz was invited to join the former vice president's
Social Democratic Power (PODEMOS) alliance as its candidate for senator. The election presented mixed results for the conservative coalition. While
Evo Morales of the
Movement for Socialism (MAS-IPSP) won the presidency, PODEMOS won the most
Senate seats.
Tenure The control exercised by the opposition over the upper chamber constituted the main counterweight to Morales's ability to legislate during his first term. Though the MAS defeated Ortiz to win the presidency of the Senate in 2006—owing to the votes of the two senators from
National Unity (UN) and the
Revolutionary Nationalist Movement (MNR)—it was unable to repeat that victory in ensuing years. In 2007, neither the MAS nor PODEMOS won control of the Senate, with Senator
José Villavicencio of UN being elected to preside over the body. By 2008, however, both the MNR and UN opted to lend their support to PODEMOS, which put forward Ortiz to hold the position, beating out the more conciliatory Carlos Böhrt for the nomination. The promotion of Ortiz as head of the upper chamber was a considerable setback for the ruling party as, compared to his more centrist predecessor, Ortiz aligned himself with more
right-wing sects of the opposition. Attempts by the MAS to dislodge Ortiz from the presidency the following year also failed, with his bid for reelection counting the support of most of the opposition and even two ruling party defectors. Throughout Ortiz's term, the Senate found itself primarily preoccupied with the ongoing process of entirely reforming the nation's
Constitution, a project spearheaded by Morales. Just over a month after assuming office, in March 2006, Ortiz voted in favor of sanctioning the
convocation of a
Constituent Assembly charged with drafting a new constitution, a decision approved unanimously by both the MAS and opposition. Inaugurated in
Sucre on 6 August, the Constituent Assembly was tasked with completing its work within a year but quickly found itself bogged down by disputes over which sections of the text necessitated two-thirds majority approval. On 3 August 2007, three days before its initially prescribed mandate expired, the Senate's four caucuses agreed to extend the Assembly's term to 14 December. Ortiz initially supported the decision, believing that the agreement consolidated the threshold of two-thirds for the approval of the document's final text. Three months later, however, amid mass protests in Sucre, the MAS majority in the assembly opted to reconvene itself in
Oruro, where the final draft was approved in a marathon session boycotted by PODEMOS. The circumstances of its passage led Ortiz to later state that the new constitution "never had legitimacy." In 2008, seeking to bolster his mandate amid continued unrest, Morales sought the support of Congress for the approval of a
recall referendum against himself and the nine departmental prefects. At internal meetings regarding the topic, the majority of the PODEMOS caucus opted to support the referendum as a means of blocking the pending enactment of the new constitution. Though Ortiz personally opposed the decision, as president of the Senate, he chose not to use his power to block the plebiscite's convocation. Ultimately, Morales survived the vote with the support of sixty-seven percent of the population, while the opposition suffered the loss of two of its prefects in
Cochabamba and
La Paz. Following its inability to remove Morales from office, the opposition reinitiated negotiations with the government. In October, the MAS and PODEMOS reached an agreement in which the opposition-controlled Senate would approve the call for a
referendum to ratify the new constitution. In exchange, the MAS conceded to the modification of over a hundred articles in the draft document and the convocation of
new general elections ahead of schedule, with Morales pledging not to seek reelection after 2009. Ortiz opposed the agreement, leading a group of around thirty parliamentarians who voted against the referendum.
2009 general election Ortiz's opposition to the new constitution led to his estrangement from Quiroga and PODEMOS, which suffered an internal implosion around this time. In March 2009, the still-president of the Senate announced his defection from the alliance, taking eleven of its Santa Cruz parliamentarians with him and establishing
Popular Consensus (CP), a regional civic group led by himself that sought to contest that year's general elections. Following the presentation of the new party, senators from both the MAS and PODEMOS called on Ortiz to resign as president of the Senate, arguing that he no longer belonged to any of the upper chamber's recognized caucuses. Ortiz refused, maintaining administrative control of the Senate for the duration of his term. In August 2009, CP and UN agreed to establish an
electoral coalition, forming the Alliance for Consensus and National Unity (UN-CP). The group nominated UN's
Samuel Doria Medina for the presidency, with Ortiz seeking reelection as UN-CP's candidate for senator. By the end of the campaign, the alliance failed to attain significant support, exiting third on election day with five percent of the vote, a margin insufficient to keep Ortiz in office for a second term.
Between terms During the
2010 regional elections, Ortiz supported the gubernatorial candidacy of Santa Cruz Prefect
Rubén Costas, aligning CP with Costas's
Truth and Social Democracy (VERDES). Shortly after assuming office, Costas appointed Ortiz to his cabinet as head of the newly established Secretariat of Institutional Coordination and Autonomous Development. While in the Costas administration, Ortiz assisted the governor in formulating the
Social Democratic Movement (MDS), a political project that sought to unite the disparate parties of the region into a single national opposition front capable of challenging the MAS. More than thirteen groups made up the movement, including Ortiz's CP, Costas's VERDES, and
Savina Cuéllar's Liberty and Renovating Democracy (LÍDER). In May 2013, the three main organizations presented a merger request to the
Supreme Electoral Tribunal (TSE), which rejected it on the grounds that the law only allowed political parties to be fused, not civic groups. To circumvent this, Ortiz's party requested authorization from the TSE to legally change its name from Popular Consensus to Social Democratic Movement, which was accepted. The decision gave rise to the MDS's formal establishment four months later at a Founding Congress in which Ortiz was elected as the party's secretary-general.
Second term (2015–2020) 2014 general election For the 2014 electoral campaign, the MDS aligned itself with UN, forming the
Democratic Unity (UD) coalition to combat the MAS as a single front. As part of its strategy of nominating former parliamentarians and politically experienced professionals to guarantee a high degree of representation in the legislature, UD selected Ortiz as its candidate for senator. The coalition attained a distant second place at the polls, returning Ortiz to the Senate to complete a non-consecutive second term.
Tenure Ortiz's tenure as a member of the opposition focused its efforts on investigating and denouncing acts of corruption within the government. "The main victims of this scandal were the indigenous peoples who saw their cause delegitimized [and] their organizations prostituted", Ortiz stated in a later
op-ed published by
Página Siete.
2019 presidential campaign As its secretary-general, Ortiz sought to position the MDS as a national political party with a view toward the 2019 general elections. For Ortiz, the prospect of not participating in the election was out of the question, with internal discussions on whether the party would go it alone or form an alliance taking place long before the start of the campaign. Should the MDS have competed on its own, the nomination of its leader, Costas, was a "natural" choice, with Ortiz profiled as a possible vice-presidential candidate. During negotiations with the
Revolutionary Left Front (FRI)—which nominated former president
Carlos Mesa—the MDS conditioned an alliance on the inclusion of Ortiz on the ticket as Mesa's running mate. The FRI rejected this option as Mesa preferred to choose his own companion, frustrating negotiations. Ultimately, the MDS settled on allying with UN, its longtime partner, effectively continuing the previous UD coalition under a new name. The alliance, dubbed Bolivia Says No (BDN), was sealed on 13 November 2018 and formally launched the following day. Shortly thereafter, BDN began analyzing whether it would nominate a single presidential ticket or if candidates from UN and MDS would separately contest the primary elections scheduled for January 2019. The latter option would have made the alliance one of the only fronts facing a competitive primary. While Doria Medina was the only presidential candidate profiled by UN, the MDS considered the likes of Costas, Ortiz, and former Beni governor
Ernesto Suárez, with the latter two also seen as "ideal" running mates. By 27 November, BDN had settled on a compromise, nominating Doria Medina for the presidency with Ortiz seeking the vice-presidency. However, within hours of the scheduled announcement, Doria Medina publicized his and his party's decision to withdraw from the alliance, instead choosing to sit out the 2019 election cycle. Two days after the rupture of the BDN alliance, the MDS presented Oscar Ortiz as its presidential candidate, with Senator Edwin Rodríguez of
Potosí as his running mate. Their campaign was officially launched on 2 January 2019, the first working day of the year. Ortiz outlined his intention to tour the entire country, conducting meetings with differing sectors of the population to present BDN's platform and hear the needs of the citizenry. Among those sharing such concerns included Ortiz's own running mate, Rodríguez, who unexpectedly withdrew his candidacy in July while Ortiz was on a campaign visit to Brazil. Nonetheless, Ortiz vehemently refused to remove himself from the race, accusing Rodríguez of having been bought by opposing candidates. A month later, BDN selected Deputy
Shirley Franco of
Cochabamba to serve as Ortiz's new running mate. Nearing the end of the campaign, BDN continued to see increasing calls for Ortiz to drop out of the race, even from among internal groups. In October, a multitude of prominent national and regional legislators, including the entirety of the MDS caucus in the Cochabamba Departmental Assembly, withdrew their support from Ortiz, calling on supporters to lend their vote to Mesa. By election day, the final results gave Ortiz little more than four percent of the vote, leaving him in fourth place, having been displaced from third by the unprecedented support attained by
evangelical pastor
Chi Hyun Chung. Following his loss, Ortiz endorsed Mesa's campaign to confront Morales in an expected second round.
Political crisis and transition No runoff ever occurred. Following the election, widespread allegations of
fraud and subsequent
mass mobilizations paralyzed the country. After three weeks of protests, continued
social unrest culminated in the resignation of Morales from the presidency, opening a vacuum of power in the country. In ensuing days, Ortiz attended a series of meetings sponsored by the
Bolivian Episcopal Conference, serving as a representative for the MDS. Per the Church's account, the MAS delegates suggested two means of presidential succession that they found acceptable, both of which were rejected as unconstitutional by the others in attendance. Conversely, both
Adriana Salvatierra and Susana Rivero—presidents of the upper and lower chambers, respectively—rejected the option of assuming the presidency themselves, nor did they accept the suggestion that
Jeanine Áñez, second vice president of the Senate, succeed Morales. With dialogue quickly proving fruitless, Salvatierra requested a closed-door meeting, attended only by herself, Rivero, and Ortiz, with Monsignor
Eugenio Scarpellini present as a mediator. The contents of the discussions were not disclosed, though, after their conclusion, the plenary meeting resumed, with Salvatierra and Rivero agreeing to facilitate Áñez's succession. With Morales's ouster, the opposition had won control of the executive. However, the new government's ability to conduct the transition remained reliant on the legislature, dominated by a MAS
supermajority. As dean of the Senate, Ortiz took charge of reestablishing dialogue with his MAS colleagues, seeking to reach agreements in the legislature with the aim of annulling the previous elections, convoking new ones, appointing new electoral authorities, and extending the government's soon-to-expire mandate. To do this, he initially sought to negotiate the necessary MAS support to be elected president of the Senate. According to Chuquisaca Senator Omar Aguilar, the option of granting Ortiz control over the upper house was supported by Efraín Chambi, head of the MAS caucus in the Senate, who was willing to exchange the position for a ministerial role, granting the MAS a presence in the executive. Aguilar opposed this idea because it would have given Ortiz virtual control over the
Legislative Assembly. Ultimately, Ortiz backed down after the MAS threatened to reinstate Salvatierra as president of the Senate, given that she had never formally resigned. With that, MAS Senator
Eva Copa was elected to preside over the chamber. Following the election of its new directorate, the Senate moved to reconfigure its committees and commissions. Ortiz was selected to serve as president of the Constitution Commission, granting him a high degree of control over the process of drafting a bill to call new elections. After a series of intensive negotiations, Ortiz succeeded in reaching an agreement with the MAS's "conciliatory wing", who agreed to pass a law scheduling new elections in which Morales would not be allowed to participate. With that, Ortiz subsequently oversaw the process of designating six new electoral authorities to chair the TSE and was one of the architects of the law extending the terms of the country's elected officials. Ortiz's ability to attain MAS support for these initiatives was due in part to the party's internal divisions and the political inexperience of its legislators. "When the technical groups that would elaborate the laws were formed, [the MAS] realized that they had never worked in that way because all the bills came from the executive and the ruling party only had to approve them", Ortiz stated. == Minister of Economy ==
