Grassroots volunteers helped Lula win Brazil's presidency

Brazil's Luiz Inacio Lula da Silva won a fourth presidential term after grassroots volunteers mobilized voters, overcoming a first-round deficit, though the result is disputed by Flavio Bolsonaro and bus disruptions in Salvador face investigation. Supporters provided free rides and boosted online campaigns after Flavio Bolsonaro led the first round. Lula's team rebooted strategy, including a WhatsApp channel that grew to over 10 million members, helping him gain more than 10 million votes between rounds. Bolsonaro, now in the US, questioned the vote's credibility and the extended voting hours. Salvador's mayor denied holding up buses, while Bahia saw nearly 400,000 additional voters, with volunteers transporting hundreds to polls.
