Peru's 2026 Election Race Tightens: Fujimori and López Aliaga in Statistical Tie

The race is not settling. Voters are moving between committed choices.
Electoral volatility in Peru's 2026 presidential race reflects shifting preferences among decided voters rather than undecided voters finally making choices.

A month before Peruvians choose their next president, the race refuses to resolve itself into clarity. Keiko Fujimori and Rafael López Aliaga now stand in statistical deadlock at the top of the field, their fortunes reversed by a single political miscalculation and the restless movement of voters who have already chosen once and are choosing again. In a democracy still searching for stable ground, this volatility is less a surprise than a mirror — reflecting a citizenry that remains deeply uncertain not about whether to participate, but about whom to trust.

  • For the first time in the campaign, Fujimori and López Aliaga are tied at the top — a deadlock born not from stagnation but from rapid, ongoing voter migration.
  • López Aliaga's 3.4-point drop traces directly to his support for censuring Prime Minister Jerí, a move most Peruvians opposed even while distrusting the official — a costly misread of public sentiment.
  • The volatility is not driven by undecided voters finally committing; committed voters are switching, meaning the floor beneath every candidate is less stable than the numbers suggest.
  • Third place is a three-way blur within the margin of error, with López Chau, Acuña, and Álvarez jostling in a space where polling noise and real movement are nearly indistinguishable.
  • Wolfgang Grozo's leap from 1.4% to 4.2% — and 12.4% among voters aged 18–24 — introduces a wildcard that could further fragment an already splintered field in the final stretch.

Peru's presidential race has entered its most turbulent phase yet. With thirty-four days until the general election, a new Datum poll broadcast on Cuarto Poder shows Keiko Fujimori of Fuerza Popular climbing to 10.7 percent while Rafael López Aliaga of Renovación Popular falls 3.4 points to 10 percent — creating the first statistical tie at the top of the race after nearly three months of campaigning.

López Aliaga's decline has a discernible cause. His decision to back the censure of Prime Minister José Jerí appears to have alienated voters who, despite harboring doubts about Jerí's integrity, preferred he remain in office through the government transition. Fujimori, meanwhile, has continued a steady upward climb, and the convergence of their trajectories has produced a genuine deadlock.

What makes this movement significant is its source. The shifts are not coming from undecided voters finally making up their minds — that pool shrank by only one point in fifteen days. Instead, voters who had already committed to a candidate are switching. This pattern points to deep electoral volatility, the kind that can reverse itself just as quickly.

Below the frontrunners, three candidates — Alfonso López Chau, César Acuña, and Carlos Álvarez — are clustered within the margin of error, making the battle for third place genuinely unresolvable by current data. The fragmentation is so pronounced that minor shifts could redraw the entire middle tier.

The most striking development may be the emergence of Wolfgang Grozo, who jumped from 1.4 percent to 4.2 percent in two weeks. Among voters aged eighteen to twenty-four, he reaches 12.4 percent — a signal that younger Peruvians are responding to something in his candidacy that has yet to reach older demographics. Whether that momentum endures or evaporates before election day is the question the final weeks will answer.

Peru's presidential race is tightening in ways that suggest the final month of campaigning will be turbulent. With thirty-four days until the general election, Keiko Fujimori of Fuerza Popular has climbed to 10.7 percent of voter intention, while Rafael López Aliaga of Renovación Popular has dropped 3.4 percentage points to land at 10 percent. For the first time, the two frontrunners are locked in a statistical tie.

The shift is the most visible sign of movement in the latest Datum poll, released through the program Cuarto Poder after nearly three months of campaigning. López Aliaga's decline appears to have a specific cause: his decision to support the censure of Prime Minister José Jerí. Polling data suggested that most Peruvians viewed Jerí with suspicion on corruption grounds, yet preferred he remain in office until the government transition occurred in the coming months. López Aliaga's backing of his removal seems to have cost him support among voters who disagreed with the move.

Fujimori, by contrast, has maintained the upward trajectory she has shown in recent measurements. Her steady gains, combined with López Aliaga's slip, have created the first genuine deadlock at the top of the race. The movement is not coming from undecided voters finally making up their minds. Instead, it reflects voters who had already chosen a candidate switching their preference to someone else. This pattern signals high electoral volatility—the kind that can shift again within days.

The competition for third place is equally fluid. Three candidates are bunched within the statistical margin of error. Alfonso López Chau holds relatively solid support. César Acuña is gaining ground. Carlos Álvarez has lost some traction. With a margin of error of plus or minus 2.5 percentage points, it is impossible to say with confidence whether these differences reflect real movement or polling noise. The fragmentation of the vote is so pronounced that small shifts in any direction could reshape the entire middle tier of the race.

One surprise has emerged in sixth place: Wolfgang Grozo, a candidate who barely registered two weeks ago at 1.4 percent, has jumped to 4.2 percent. The gain is striking, particularly among voters aged eighteen to twenty-four, where he reaches 12.4 percent. His sudden visibility suggests that younger voters are responding to something in his message or persona that older voters have not yet embraced. Whether this momentum holds or fades in the coming weeks remains unclear.

The undecided voter pool remains at historically elevated levels. In the past fifteen days, this group shrank by only one percentage point—a change so small it could easily fall within the margin of error. The category of "other candidates" has grown slightly, with individual movements small but collectively adding more than a point. What matters most is what this volatility reveals: the race is not settling. Voters are moving between committed choices, not gradually resolving their uncertainty. The electoral board is still in motion, and everything suggests it will continue to shift as the campaign enters its final stretch.

The movements observed do not come from undecided voters finally deciding, but from voters switching preference between candidates they had already chosen—a sign of high electoral volatility.

Why would López Aliaga's support for censuring the prime minister cost him votes when most people distrusted the prime minister anyway?

Model

Because voters distinguished between what they thought of Jerí as a person and what they wanted to happen politically. They didn't trust him, but they also didn't want the disruption of removing him weeks before a transition. López Aliaga read the room wrong.

Inventor

So this isn't about undecided voters finally picking sides?

Model

No, it's the opposite. The undecided pool barely moved. What we're seeing is people who had already committed to a candidate switching to someone else. That's much more volatile and unpredictable.

Inventor

What does Wolfgang Grozo's surge tell us?

Model

That there's an opening among young voters for something different. He went from invisible to 12.4 percent among eighteen to twenty-four year-olds in two weeks. Whether that's sustainable or a flash is the real question.

Inventor

Is there any stability in this race at all?

Model

The only stable thing is the instability. Fujimori's upward trend has been consistent, and López Chau seems to have a floor. But everything else is moving. With a month left, expect more surprises.

Inventor

What would it take for one of these candidates to actually pull away?

Model

A major event, a gaffe, or for one of the middle-tier candidates to collapse and consolidate their voters behind someone. Right now the vote is too scattered for anyone to build a real lead.
