The 2025 Unidad por Chile presidential primary was held in Chile on June 29, 2025, to choose the presidential candidate of the Unity for Chile coalition, which backed the government of President Gabriel Boric, for the 2025 Chilean general election. Four candidates competed: Jeannette Jara, a former labor minister from the Communist Party; Carolina Tohá, a former interior minister from the Party for Democracy who ran on behalf of the Democratic Socialism bloc; Gonzalo Winter of the Broad Front; and Jaime Mulet of the Social Green Regionalist Federation. Right-wing parties did not hold a primary.

Jara won with 60.2 percent of the vote, followed by Tohá with 28.1 percent, Winter with 9.0 percent, and Mulet with 2.7 percent. Tohá had led early polling, and Jara's margin surprised many observers. Turnout was low, at about 9 percent of eligible voters. Jara became the first Communist Party member to head a ticket backed by the traditional center-left. She finished first in the November 16 general election but lost the December 14 runoff to José Antonio Kast.

Background Unity for Chile is a left-of-center coalition that, at the time of the primary, included the Socialist Party, the Party for Democracy, the Liberal Party, the Radical Party, Humanist Action, the Communist Party, the Broad Front, and the Social Green Regionalist Federation. The coalition faced the 2025 election with the Boric government unpopular: a Cadem poll in late June 2025 put presidential approval at 32 percent and disapproval at 61 percent. Opposition candidates on the right, led in polls by Evelyn Matthei of Chile Vamos and Kast of the Republican Party, dominated early surveys.

The parties' preferred scenario was a candidacy by former president Michelle Bachelet, around whom the whole bloc could unite. When she hesitated, Tohá resigned from the cabinet and then worked to arrange a competitive primary, personally recruiting Winter to run.

Electoral rules The primary was run by the state Electoral Service (Servel). Voting was voluntary, as in all Chilean primaries, whereas voting in general elections has been compulsory since 2022. Participation was open to unaffiliated voters and members of the participating parties, which excluded only formal members of parties that did not take part. Unity for Chile was the only bloc to field candidates, as the right chose to go directly to the general election.

Timeline Parties and coalitions registered their primary candidates with Servel by April 30, 2025. Public and online advertising was permitted from May 30, and televised campaign spots began on June 11. Campaigning ended at midnight on June 26, followed by a blackout period and a ban on political events from June 27. The Armed Forces took over responsibility for public order at polling stations on June 28.

Selection of the field

Tohá. Interior Minister Carolina Tohá resigned from the cabinet on March 4, 2025, to seek the presidency, becoming the first prominent center-left figure to enter the race. Socialist Party president Paulina Vodanovic had also been nominated by her party's central committee, but the Liberal Party (on April 21) and the Radical Party (on April 26) backed Tohá, and the Socialists ultimately did the same. Winter. The Broad Front's central committee nominated Winter unanimously on April 3, after Maipú mayor Tomás Vodanovic repeatedly declined to run. Winter, born in 1987, had served as a deputy for Santiago's 10th District since 2018. Jara. The Communist Party did not nominate Jara at a central committee meeting in late March. Some in the party wanted former Recoleta mayor Daniel Jadue, who was under house arrest awaiting trial in the Farmacias Populares case, to run instead. After the party's political commission voted in early April, with Jadue winning only two votes, Jara became the nominee. Mulet. Deputy Jaime Mulet, nominated by his federation in January, had hoped to organize a separate primary with the Christian Democrats, but those talks failed and he joined the Unity for Chile primary.

Campaign Dynamics After the candidates registered, Tohá led polls with roughly double the support of her rivals and near-universal name recognition. Jara, by contrast, polled no higher than 5 percent until mid-May. Her campaign gained momentum after she formalized a team and strategy at the start of that month, aimed at taking younger voters from Winter, older voters from Tohá, and holding the Communist base. Her inner circle kept its distance from some of the party's harder-line figures; she rejected a proposal to bring Jadue into her campaign team. One analysis argued that Jara avoided the sparring between Winter and Tohá, while her modest background contrasted with those of her opponents.

The Broad Front's campaign advertisement, which portrayed the post-dictatorship governments of the Concertación in a critical light, drew a sharp reply from Tohá and set off a dispute over the legacy of that period. Boric had asked Tohá to keep her tone from undermining coalition unity, and she initially avoided confrontation. As Jara rose in the polls, Tohá's advisers urged her to focus on differences with Jara, and she said in a television interview that she did not favor the Communist Party governing, a remark that irritated both communists and socialists.

Debates The candidates met in several debates, including one hosted by Radio Duna and La Tercera on June 5 and the first televised debate, on Canal 13, about two weeks before the vote. In the latter, rivals questioned Jara about her party membership, and Winter asked whether she would resign from the party if she won. A debate organized by The Clinic and Radio Pauta on June 16 covered the candidates' programs and the friction among them, including Tohá's management of the security crisis as interior minister.

Platforms According to Americas Quarterly, Jara campaigned on a further increase in the minimum wage, state-led development including resource nationalism in critical minerals, higher taxes on high earners, and the eventual end of Chile's private pension system. She also called for suspending diplomatic relations with Israel. She had said Venezuela is an authoritarian regime, while describing Cuba as having a democracy "different from ours". Tohá's moderate positions resembled those of the Bachelet-era left, but her record on crime, which was her responsibility as interior minister, weighed on her candidacy, since security remained voters' top concern. Jara drew on achievements under her ministry, including a reduction of the standard workweek from 45 to 40 hours and a pension reform.

Turnout About 1.4 million people voted, below even optimistic expectations of around 2 million. Left-wing commentary compared this unfavorably with roughly 1.7 million participants in 2021. Right-wing candidates Johannes Kaiser and Evelyn Matthei both said the turnout showed public distance from politics and disappointment with the government. Jara replied that participation could not be judged harshly in a wholly voluntary vote and said she preferred to see the result positively. Her personal vote came within about 2,000 votes of Sebastián Piñera's total in the 2017 Chile Vamos primary.

Aftermath Reactions and analysis In her victory speech, Jara thanked her rivals, whom she had embraced on stage, and invoked former president Salvador Allende. Boric congratulated her and urged the coalition to broaden its appeal. Jara said she would seek to attract the Christian Democrats.

The result marked the first time since Chile's return to democracy that the traditional center-left parties lined up behind a Communist presidential candidate. Analyst Nicolás Saldías described it as a blow to the traditional center-left and a sign of a more polarized general election. He drew a parallel with Zohran Mamdani's victory in the New York City Democratic mayoral primary, noting that both winners had defeated establishment figures who had appeared to be front-runners. Observers also noted that Jara's identity as a Communist and the Boric government's low approval would be obstacles in the general election. Winter, whose result was widely described as poor for the Broad Front, was later reelected to the Chamber of Deputies in the 2025 parliamentary elections.

General election

Jara placed first in the November 16 first round with about 27 percent, ahead of Kast with about 24 percent, but no candidate won outright. With Matthei's and Kaiser's supporters expected to back Kast, her path to a runoff win was seen as narrow. Kast won the December 14 runoff with 58 percent of the vote to Jara's 42 percent.
