Oct 15, 2026

Brazilian General Elections of 2026: general trends of the first round of results – Luiza Aikawa – On Sunday, October 4, 2026, the Brazilian population went to the polls to vote in the general elections for state and federal deputies, governors, senators, and the president. The vast majority of the contested seats had their results published by the end of the same day, with the exception of the few gubernatorial races that, like the presidential dispute, went to a runoff.

Reviews

“Pex-Network is a valuable and rigorous source for specialists and all those interested in debating, learning, and keeping up to date about world leaders and executive politics around the globe. In a nutshell: a terrific blog!”

Michelangelo Vercesi
University of Naples Federico II

“PEX es una fuente imprescindible para explorar la agenda de investigación sobre el Poder Ejecutivo con valiosas contribuciones de reconocidos académicos, investigadores y expertos de distintos países. Las publicaciones aportan, desde una pluralidad enfoques, un análisis de cuestiones contemporáneas que contribuye a profundizar el conocimiento sobre el campo.”

Maria Eugenia Coutinho

“The PEX-Network blog makes the world smaller, as its contributors sort out what is different and not-so-different in politics around the globe. As a scholar of the U.S. Presidency, I gain much from its posts, including coming to understand what is similar about the American presidency to other countries, and therefore isolate what is different.”

Daniel Ponder
Drury University – US

“Os estudos sobre as instituições experimentaram recentemente importante inflexão com a inclusão de pesquisas sistemáticas sobre a estrutura de funcionamento do Poder Executivo. O trabalho do PEX Network é pioneiro nesta linha, no Brasil, com alto impacto científico, aqui e alhures.”

Fabiano Santos
Instituto de Estudos Sociais e Políticos (IESP-UERJ)

“The blog is an important way to connect students of executive politics across the Americas and beyond – in an era of disinformation, it serves as a crucial network providing hard data and scholarly community.”
