Will Brazil go back to Bolsonaro? Lula finds new challenger in jailed ex-president's son Flavio

A new poll shows Senator Flavio Bolsonaro has emerged as the main challenger to President Lula, narrowing Lula's lead to just four points in a simulated runoff. First-round polling indicates Bolsonaro's support is rising, reflecting shifting voter sentiment ahead of the October 2026 election. Flavio's momentum is fueled by conservative voters rallying behind him and growing dissatisfaction with Lula's administration.
