Peru presidential election matchup

A direct comparison of party strength is constrained by available data. Specific affiliate counts and comprehensive figures for regional or municipal candidates filed with the Jurado Nacional de Elecciones (JNE) by the Q4 2025 deadline were not detailed in the provided sources for any of the parties. Therefore, a definitive assessment of the relative strength of party machinery, as measured by these specific criteria, cannot be precisely determined from the available information.

Keiko Fujimori's Fuerza Popular faced scrutiny regarding affiliate signatures. The National Registry of Identification and Civil Status (Reniec) reported over 2,000 false signatures submitted by the party to the JNE for affiliation ^{[^]}. Fuerza Popular was also among 32 parties identified by Reniec with observed signature issues ^{[^]}. Despite these integrity concerns, the Special Electoral Jury (JEE) declared the presidential formula for Fuerza Popular inscribed after it successfully overcame the objection period ^{[^]}. However, the sources did not provide specific numbers for their successfully registered affiliates or regional/municipal candidates for the 2026 elections.

Other candidates' parties also lacked specific data on affiliates and candidates. Rafael López Aliaga is identified as the presidential candidate for Renovación Popular ^{[^]}, with information noting internal elections for 2025 that would involve candidate selection ^{[^]}. However, specific data on successfully registered party affiliates or filed regional/municipal candidates for Renovación Popular were not available. Similarly, while Roberto Sánchez Palomino's Juntos por el Perú had its padrón of affiliated electors approved by the JNE for the primary elections of the 2026 Regional and Municipal Elections ^{[^]}, a specific numerical count of successfully registered affiliates or regional/municipal candidates filed was not provided for this party either.

Carlos Álvarez demonstrated significant positive momentum in voter intention by Q1 2026. Based on a comparative analysis of public opinion from Q2 2025 to Q1 2026, Roberto Sánchez and Carlos Álvarez exhibited the most significant positive momentum in capturing voter intention. By late March 2026, La República reported a notable rise for Carlos Álvarez to third place in voting intention, signaling a clear upward trend in his public appeal. During this period, established contenders such as Keiko Fujimori and Rafael López Aliaga experienced a stagnation in their support ^{[^]}.

Roberto Sánchez showed substantial momentum, challenging established political figures. Further data from early April 2026 highlighted Roberto Sánchez as demonstrating significant momentum, displacing Rafael López Aliaga and strongly positioning him to advance to a second-round runoff ^{[^]}. This considerable gain against a prominent candidate suggests Sánchez was effectively drawing a broad base of support, likely including voters seeking alternatives to traditional political figures and expressing anti-establishment sentiment ^{[^]}.

Shifts in voting intention strongly indicate broader public recognition. While specific metrics such as net sentiment or share of voice across all media outlets are not explicitly detailed, the reported shifts in voting intention by major outlets like La República ^{[^]}, Encuestas Perú ^{[^]}, El Machete Perú ^{[^]}, and Futbolperuano.com ^{[^]} serve as strong indicators of growing public recognition and positive momentum for these emerging candidates. The concurrent stagnation of established candidates underscores a dynamic period where a segment of the electorate was actively seeking and consolidating support behind new political options.

Recent developments significantly altered the investigation status of Keiko Fujimori. The Equipo Especial Lava Jato, which previously handled the 'Cócteles' case, was deactivated on January 6, 2026 ^{[^]}. Following this, on January 14, 2026, the prosecutor assigned to the 'Cócteles' case was suspended, and a report indicated the case against Fujimori had been archived ^{[^]}. However, on the same day, a judge maintained the imputation against her for false declarations of contributions to the ONPE ^{[^]}. Earlier, a 35-year imprisonment request had been sought in the 'Cócteles' case ^{[^]}, and Keiko Fujimori, along with Fuerza Popular and her presidential ticket, remains under investigation for money laundering ^{[^]}.

Rafael López Aliaga faces two ongoing money laundering investigations. Companies linked to López Aliaga are currently under investigation in connection with the 'Panama Papers' ^{[^]}, and the Judicial Power admitted an appeal seeking to revoke the extension of this investigation ^{[^]}. Additionally, on March 21, 2026, the anti-corruption prosecutor's office initiated an investigation into López Aliaga regarding the S/ 4 billion debt of the Metropolitan Municipality of Lima ^{[^]}. For either of López Aliaga's investigations, no specific prosecutorial deadlines or judicial rulings before the official candidate registration period are available in the provided information.

Juntos por el Perú (JPP) prioritizes second-round alliances over first-round unity. Roberto Sánchez Palomino's JPP has engaged in coalition-building, exemplified by the "Alianza ASI – Juntos por el Perú" ^{[^]}. However, a unified left-wing ticket for the first round of elections appears improbable. Sánchez has explicitly stated that his dialogues with five political parties ^{[^]} are geared towards forming alliances for an "eventual second round" ^{[^]}, particularly to counter a candidate such as Fujimori ^{[^]}. This strategic emphasis indicates that JPP's main objective is not to consolidate a broad left-wing movement for the initial electoral phase.

The left-wing vote in Peru is highly probable to be split. Perú Libre (PL) has independently registered Vladimir Cerrón as its presidential candidate, an announcement made while he was in hiding ^{[^]}. The relationship between JPP and PL is notably strained, as illustrated by Cerrón's public criticism of Sánchez, whom he described as "the system's new trial balloon" ^{[^]}. This internal discord, combined with a highly fragmented electoral landscape featuring 36 registered presidential tickets for the General Elections ^{[^]}, strongly suggests a division of the left-wing vote in the first round.

Peru's electoral calendar established key deadlines for candidate selection and registration. The official electoral calendar, known as the Cronograma Electoral, was established by the Jurado Nacional de Elecciones (JNE) for the 2026 General Elections, outlining crucial dates and procedural requirements ^{[^]}. The period for political parties to conduct their internal primary elections for candidate selection concluded between November 10 and November 24, 2024 ^{[^]}. Subsequently, the definitive deadline for the formal registration of presidential tickets (fórmulas presidenciales) was set for January 10, 2025 ^{[^]}.

Several parties face uncertainty regarding their formal election eligibility. As of early January 2026, while 32 presidential slates have reportedly been inscribed, several parties are still awaiting the resolution of challenges (tachas) filed against their submitted candidate slates ^{[^]}. This ongoing review process will determine their full registration and eligibility to participate in the elections. For example, parties such as Avanza País and Perú Primero are currently undergoing these evaluations ^{[^]}. Consequently, despite the official registration deadlines having passed, some parties have not yet completely cleared all procedural requirements ^{[^]}.
