Peru's polarized runoff: Fujimori vs. Sánchez in bid for presidency amid voter exhaustion

The arithmetic of exhaustion—a nation worn down by political chaos
Fewer than three in ten Peruvians voted for either finalist in the April first round, reflecting deep voter disillusionment.

On Sunday, Peruvians choose between two candidates who together earned the support of fewer than one in three April voters — a quiet testament to how thoroughly a decade of political collapse has hollowed out public faith in governance. Eight presidents in ten years, most of them unelected, have left a nation not so much choosing its future as bracing for it. The contest between Keiko Fujimori's authoritarian inheritance and Roberto Sánchez's leftist promise is less a democratic mandate than a forced reckoning with exhaustion itself.

  • More than six million Peruvians skipped the first round despite facing fines, and three million more deliberately spoiled their ballots — a protest vote that, if counted, would have outpaced either candidate.
  • A country that has cycled through eight presidents since 2016 — most of them unelected — now faces a runoff between two figures who together represent only 29 percent of April's electorate, deepening the legitimacy crisis.
  • Fujimori's law-and-order campaign draws on her father's authoritarian legacy even as it is shadowed by it — he died having served 16 years in prison for kidnappings and murders committed under his rule.
  • Sánchez courts rural voters by invoking the ousted and jailed Pedro Castillo, promising a new constitution and Castillo's freedom, while already retreating from bolder economic pledges under institutional pressure.
  • Polls show the two candidates statistically tied near 43 percent each, meaning the next president of Peru will be decided by the thinnest of margins with the weakest of mandates.

Peru's voters head to the polls Sunday to choose between two candidates who together captured less than three in ten votes in April — the arithmetic of a nation worn down by political chaos. More than six million people skipped the first round entirely despite fines for abstention, and another three million spoiled their ballots in deliberate protest. Had those spoiled votes been tallied as a single candidate, they would have won.

This is Peru's ninth presidential election in a decade. Eight presidents have come and gone since 2016, only three of them actually elected. The most recent, José Jerí, faced accusations of influence-trafficking with Chinese businessmen; his replacement, the 83-year-old current president José María Balcázar, is best known for supporting child marriage. Institutional collapse here is not abstract — it is something Peruvians have watched happen, repeatedly, in real time.

Keiko Fujimori, running for the fourth time, has built her campaign on law and order and her father's reputation for an iron fist. But Alberto Fujimori spent 16 years in prison for authorizing kidnappings and murders before dying in 2024, and many voters fear his daughter would govern as an authoritarian who would not respect the separation of powers.

Roberto Sánchez has claimed the mantle of Pedro Castillo — the leftist president ousted in 2022 after attempting to dissolve congress, later sentenced to over eleven years for rebellion. Sánchez wears Castillo's trademark sombrero at rallies, promises a new constitution, and vows to free his predecessor. He has already walked back a pledge to remove the central bank chief, a signal of the constraints awaiting him.

Polls place them statistically tied near 43 percent each. Sociologist Santiago Pedraglio puts it plainly: politicians have lost their credibility, and almost no one trusts them anymore. Harvard political scientist Steven Levitsky says popular discontent has moved beyond anything seen two decades ago — now, he says, it is through the roof. Whoever wins on Sunday will inherit a country where the machinery of government has been broken so many times that voters have largely stopped believing it can be repaired.

Peru's voters will walk into polling stations on Sunday to choose between two candidates who together captured less than three in ten votes cast in April. This is the arithmetic of exhaustion—a nation so worn down by political chaos that it has narrowed its choice to a stark left-right binary, each option carrying its own weight of fear.

Keiko Fujimori, the daughter of the late authoritarian president Alberto Fujimori, won 17 percent in the first round. Roberto Sánchez, a 57-year-old congressman and former trade minister, took 12 percent. Between them, they represent the votes of roughly 29 percent of Peruvians who bothered to cast ballots in April. More than 6 million people did not show up at all, despite fines for abstention. Another 3 million spoiled their ballots in protest—blank or deliberately unreadable. If those spoiled votes had been counted as a single candidate, they would have won.

This is Peru's ninth presidential election in a decade. The country has cycled through eight presidents since July 2016, and only three of them were actually elected. The others inherited the office through the machinery of congressional succession, most of them unsuited to it. The last one, José Jerí, was accused of influence-trafficking in secret meetings with Chinese businessmen. His replacement, the current president José María Balcázar, is 83 and best known for supporting child marriage. The instability is not theoretical. It is the lived experience of voters who have watched their government collapse and reconstitute itself again and again.

Fujimori is running for the fourth time. She entered politics at 19, named first lady when her parents' marriage dissolved during her father's 1990s rule. She has built her campaign on law and order, capitalizing on her father's reputation for an iron fist—a mano dura—as Peruvians face surging extortion and murder rates. Her party, Fuerza Popular, holds more seats in congress than any other. But she carries her father's shadow: he spent 16 years in prison for authorizing kidnappings and murders during his government's war on terrorism before dying in 2024. Voters fear she would govern as an authoritarian, that the separation of powers would not survive her presidency.

Sánchez has claimed the legacy of Pedro Castillo, the leftist president ousted in December 2022 after attempting to dissolve congress and rule by decree. Castillo was sentenced to 11 years and five months in jail for rebellion in November 2025. Sánchez has picked up rural support by wearing Castillo's trademark sombrero and arguing that Castillo was the victim of a coup plot. He promises to free Castillo, restore government to the people, and draft a new constitution. But he has already backed away from an earlier pledge to remove the central bank chief, a sign of the constraints he would face. Voters fear he would govern incompetently, as Castillo did.

Polls show them statistically tied: Sánchez at 43.8 percent, Fujimori at 43.2 percent, according to an Ipsos survey published Thursday. The margin is within the noise. Santiago Pedraglio, a sociologist at Lima's Pontifical Catholic University, said the core problem is simple: "Politicians have lost a lot of credibility, and very few people trust them any more." If voting were not mandatory in Peru, he added, abstention would be far higher. Steven Levitsky, a Harvard political scientist, told a Peruvian newspaper last month that popular discontent and mistrust have moved beyond what they were two decades ago. "Now it's through the roof," he said.

Sunday's vote will determine whether Peru moves toward authoritarian governance under Fujimori or leftist reform under Sánchez. Both paths carry institutional risk. Both candidates represent a fraction of the electorate. And both will inherit a country where the machinery of government has been broken so many times that voters have stopped believing it can be fixed.

Politicians have lost a lot of credibility, and very few people trust them any more. If voting weren't mandatory in Peru, the abstention rate would be much higher.

Why does it matter that Fujimori and Sánchez together represent only 29 percent of the first-round vote?

Model

Because it shows the scale of the rejection. Peruvians didn't choose these two—they were the last ones standing. More people spoiled their ballots in protest than voted for either finalist. That's not a mandate. That's a cry of despair.

Inventor

What does mandatory voting tell us about the state of Peruvian democracy?

Model

It tells you that without legal coercion, the system would collapse entirely. Six million people didn't vote despite fines. Three million more voted blank. The state has to force participation because people have stopped believing the exercise matters.

Inventor

Is Fujimori's promise of tough-on-crime governance actually appealing to voters, or is it just the lesser of two evils?

Model

It's appealing because crime is real and rising. Extortion and murder are not abstract problems. But it's also appealing because her father's name is attached to order, even if that order came through authoritarian means. Voters are choosing between fear of crime and fear of authoritarianism.

Inventor

Why would Sánchez back down on removing the central bank chief if he wins?

Model

Because he'd be constrained by reality. Castillo tried to govern by decree and was ousted. Sánchez is learning that even a president with a mandate—which he doesn't have—can't simply remake institutions. He's already compromising before he takes office.

Inventor

What happens if turnout is even lower on Sunday?

Model

The winner's legitimacy becomes even thinner. They'll inherit a country where the majority has either abstained or voted against them. Governing becomes harder, not easier. And the cycle of instability likely continues.
