Heading into the runoff election, Bolsonaro received the support of most of the leaders of Brazil's most traditional party.

Ahead of the upcoming second-round presidential runoff in Brazil scheduled for Sunday, October 25, Senator Flávio Bolsonaro has received the endorsement of the majority of regional directorates of the Brazilian Democratic Movement (MDB), the country's most traditional party. Additionally, recent polling compilations from Poder360 indicate that Flávio Bolsonaro leads in seven out of eight national electoral surveys, though rival candidate Luiz Inácio Lula da Silva continues to contest the race.

Simultaneously, Brazil's Superior Electoral Tribunal (TSE) convened representatives from the campaigns of Lula and Flávio Bolsonaro to address a surge in complaints regarding digital content dissemination. The electoral authority issued warnings to both campaigns as tensions escalate over social media messaging during the final stretch of the runoff contest.
