Brazilian President Luiz Inácio Lula da Silva won reelection after finishing second in the first round. Analysts credited the turnaround to lawmaker André Janones’s intensive digital campaign, which used WhatsApp, viral videos, hashtags, and livestreams to boost Lula’s online reach. The Brazilian congressman’s mobilisation strategy drew on viral videos, hashtags and coordinated online tasks, while analysts say changes in Lula’s messaging and grassroots campaigning.
