Wilson Santamaría

With his vice-ministerial tenure concluded, Santamaría returned to electoral politics, participating in the launch of Rafael Quispe's 2021 gubernatorial bid. For the accompanying municipal election, Santamaría was considered as a possible La Paz mayoral candidate on behalf of Somos Pueblo. He came close to receiving the nomination, appearing on Quispe's shortlist of potential candidates, alongside Eduardo León and Iván Arias, who ultimately won the nomination and, later, the mayoralty. Blocked out of contesting the mayoralty himself, Santamaría instead accompanied Quispe in the gubernatorial race, seeking a seat in the La Paz Departmental Legislative Assembly. Although Somos Pueblo's not-insignificant third-place finish did net it representation in the legislature, Santamaría's bottom-of-the-list placement on the party's electoral list meant that he was not among those elected.

With the campaign underway for the 2019 general election, Santamaría and Quispe joined forces with the MDS to support the presidential candidacy of Oscar Ortiz. While Quispe bided his time with a view toward contesting the La Paz governorship, Santamaría sought reelection to the Chamber of Deputies. However, he was denied a second term at the ballot box amid a nationwide underperformance for the MDS, which took home fourth nationally and dropped to fifth in La Paz.

As his term went on, Santamaría progressively disassociated himself from UN. He resigned as the party's municipal leader in 2018 and ceased participating in internal party meetings altogether just a few months later. Simultaneously, he also developed relations with partisans of the MDS, supporting the election of one of its members, Gonzalo Barrientos, to succeed him as caucus leader. However, Santamaría's most important relationships were with other independently-minded UD deputies. In particular, he, along with Amilcar Barral and Rafael Quispe, were noted as having "closed ranks as a trio," with the former two having previously defended Quispe in court years prior. When Santamaría definitively split from UN in early 2019, he did not join the MDS but rather became a member of Quispe's party, Somos Pueblo.

Entering parliament, Santamaría was selected to serve as deputy leader of the UD caucus for the 2016–2017 term. Promoted to full leader the following year, Santamaría's term contended with the eternal divisions of the UD caucus, a grouping that operated less as a unified force and more as a collection of competing parties. Given the task of wrangling opposing factions, Santamaría faced criticism for his apathetic leadership style, opting to travel abroad while legislators back home squabbled amongst themselves over important committee assignments.

An active partisan of the National Unity Front (UN), Santamaría served as the party's municipal leader for La Paz. In 2014, he was elected to represent the Department of La Paz in the Chamber of Deputies on behalf of the Democratic Unity (UD) coalition, an alliance between UN and the Social Democratic Movement (MDS). As part of their shared pact, UN and the MDS had given one another ample autonomy to define their own electoral lists in the regions where they held the highest presence, giving La Paz-based UN greater sway over UD's candidates in the department.

Wilson Pedro Santamaría Choque (born 9 September 1981) is a Bolivian lawyer, politician, and sociologist who served as vice minister of public security from 2019 to 2020. A graduate of the Higher University of San Andrés with extensive postgraduate studies, Santamaría entered the political field as a partisan of the National Unity Front and served as the party's municipal leader for La Paz. In 2014, he was elected as a party-list member of the Chamber of Deputies, representing the La Paz Department from 2015 to 2019. In parliament, Santamaría split with National Unity, reorienting himself towards the Social Democratic Movement and establishing a close personal relationship with colleague Rafael Quispe, whose party, Somos Pueblo, he joined. Following a failed second term bird in 2019, Santamaría entered the Áñez administration as vice minister of public security and served briefly as acting minister of government for a day between the removal and reinstatement of Arturo Murillo. Upon the conclusion of his tenure, Santamaría supported the gubernatorial campaign of Quispe and ran unsuccessfully for a seat in the La Paz Departmental Legislative Assembly.
