An electoral career and an early departure
Taddei announced her resignation on October 25 and submitted it to the Chamber of Deputies on October 26, 2026. According to Wikipedia, Blanca Cruz García succeeded her at the INE.
Her tenure began on April 4, 2023, when she became the first woman to lead the institute. The appointment was supposed to last nine years, through 2032. Deputies selected her by lottery from five finalists on March 31, 2023, after failing to muster the required two-thirds majority.
Before taking the national post, Taddei had spent nearly three decades working in electoral institutions, including pioneering work on Mexico's voter registry and photo voter list. She led Sonora's State Electoral and Citizen Participation Institute from 2014 to 2021, then headed the Sonora Institute for Information Transparency.
Questions about her relatives' connections to Morena and Andrés Manuel López Obrador arose soon after her selection. López Obrador, then president, said he knew the Taddei family but did not personally know Guadalupe. He also corrected reports about a circulated photograph: the woman pictured was the wife of Guadalupe's cousin Jorge Luis Taddei Bringas, not the incoming INE president.
Family positions and reported pay
El Universal's reporting traces two prominent branches of the family: Guadalupe's and that of Jorge Luis, an academic who supported López Obrador's political movement before Morena existed. Relatives have worked in electoral administration, legislatures, welfare programs, infrastructure, administrative justice, sports, environmental protection and research.
The newspaper noted that relatives holding government jobs does not, by itself, establish an irregularity. Public scrutiny has focused on how many posts the family has held, their seniority and some members' proximity to Morena governments. The spread of appointments coincided with López Obrador becoming president in 2018 and Alfonso Durazo winning the Sonora governorship in 2021, although Guadalupe's electoral career and Jorge Luis's political involvement predated those victories.
In a review of Mexico's National Transparency Platform published on October 30, 2026, El Universal put the annual taxpayer cost of salaries for Guadalupe and at least seven relatives in federal and Sonora positions at close to 12 million pesos. Her own annual gross salary was 4.7 million pesos.
The review reported net annual income of 1,661,928 pesos for her son Luis Rogelio Piñeda Taddei, Durazo's private secretary. Pablo Daniel Taddei Arriola reported 1,749,519 pesos in 2025, while Jorge Luis Taddei Bringas reported 1,229,000 pesos.
From Welfare programs to LitioMx
Jorge Luis Taddei worked as a professor and researcher at the University of Sonora and supported López Obrador's movement for years. Following the 2018 elections, he became the Secretariat of Welfare's Development Programs delegate in Sonora.
He resigned on November 3, 2023, to seek a Morena Senate nomination, but reversed course less than two weeks later. On November 15, he announced that he would not compete and would remain in charge of the Welfare delegation to finish the term alongside López Obrador.
His son Pablo Daniel was named director general of Litio para México (LitioMx) in 2022. The state-owned company was established after the López Obrador administration pushed to nationalize lithium extraction. El Universal reported that Pablo remained in charge despite the company having extracted no lithium.
Dossier Político reported that, as of late 2026, LitioMx depended on federal funding and had neither revenue of its own nor productive investment. Its third-quarter 2026 financial statements recorded receipts of 10,786,721 pesos, with 10,111,504 pesos, or 93%, spent on salaries and benefits. The director general's assigned gross monthly salary for 2026 was 177,970 pesos.
The proposed 2027 budget would provide LitioMx with 15,534,224 pesos. Its first real investment in lithium extraction is projected for 2028.
Other members of Jorge Luis's branch include his daughter Ivana Celeste Taddei Arriola, who represented Morena in the Sonora Congress during the 2021–2024 term. Jorge Carlos Taddei Arriola held jobs at the National Commission for Protected Natural Areas, including roles involving regional operations.
Posts held by Guadalupe's children and other relatives
Luis Rogelio Piñeda Taddei's move into Durazo's office followed a January 2025 announcement placing him in the Sonora government's Legal Counsel's Office. He became the governor's private secretary months later.
Another son, Jorge Francisco Piñeda Taddei, has worked in administration at Sonoran institutions. His roles include work linked to payroll management at the state Institute for Scholarships and Educational Credit; he was previously associated with the Sonora Congress's investigations area. León Fernando Piñeda Taddei served as a recording secretary at the Sonora Administrative Justice Tribunal before taking positions at the National Commission for Physical Culture and Sports.
The family's research and youth-policy roles include Isabel Cristina Taddei Bringas's work at the Center for Research in Food and Development and Luis Alonso Taddei Torres's former position directing Studies and Projects at the Sonora Youth Institute.
Jorge Luis's brother-in-law, Álvaro Bracamonte Sierra, served as secretary of government under Durazo. Paloma Bracamonte Taddei works in a construction-related area within Sonora's Secretariat of Infrastructure and Urban Development.
Durazo defends the appointments
On October 29, 2026, Durazo, a Morena governor, rejected the characterization of a Taddei clan embedded in government. While acknowledging that he had recommended or intervened in several relatives' appointments, he said that if such a clan existed, he was its unwitting architect.
Durazo said he would retain Rogelio Piñeda as his private secretary as long as no investigation linked him to wrongdoing. He also defended Pablo Taddei's performance at LitioMx, attributing the absence of production to litigation over mining concessions.
