WhatsApp Army with 10.8 Million Followers Pivoted Brazil Election for Lula

Brazil’s President Luiz Inácio Lula da Silva secured a re-election victory that allies attribute to a massive digital mobilization effort on WhatsApp. The channel, known as Lula's Army, grew to 10.8 million followers during the critical three-week period leading up to the second round of voting. This surge helped reverse a deficit against right-wing challenger Flávio Bolsonaro.

Congressman André Janones led the operation. He instructed followers to share campaign videos, promote specific hashtags, and recruit new voters. The channel provided ready-made templates for supporters to send to friends and family. Each template assigned a specific task to boost the campaign's visibility online. Janones used urgent language in these messages, telling supporters to blow up the latest video or help a new hashtag take off. Instructions included phrases such as 'Guys, urgent!' and 'No food before the mission!'

The rapid growth of Lula's Army reversed a long-standing imbalance in Brazilian politics. For years, conservatives aligned with former President Jair Bolsonaro dominated online political mobilization, particularly on WhatsApp and Telegram. Social media has played a central role in Brazilian campaigning since Bolsonaro’s 2018 election victory. The emergence of a left-wing channel with such a large following convinced many supporters that the Workers' Party had finally found a way to compete in the digital arena.

On the eve of the election, Janones hosted a 24-hour live event called the turnaround livestream. He maintained this presence even as polls continued to suggest a victory for Bolsonaro. Some members of the Workers' Party worried that Janones's confrontational style on social media could undermine the moderate image they hoped to project for Lula. Despite these internal concerns, the tactic contributed to the campaign's momentum.

In his victory speech, Lula referred to Janones as our General. He thanked the congressman for raising the morale of our troops every day. Lula acknowledged that the election had taught him many lessons. He pledged to change the way Brazil is governed and stated that digital communication would play a much bigger role in his next government. He said the administration would give people a greater say in decision-making.

Political scientists caution that measuring the exact electoral impact of online mobilization is difficult. While Lula's allies credit the WhatsApp channel with fueling the comeback, experts note it is impossible to determine how many votes were directly influenced by the operation. Political scientist Denilde Holzhacker argues that a shift in Lula's campaign strategy was the key factor. She says the campaign succeeded by connecting digital campaigning with grassroots mobilization on the ground.

According to Holzhacker, the Workers' Party candidate intensified local efforts and adapted its messaging. The campaign linked a potential Bolsonaro victory with concerns about changes to social programs and the loss of rights. Holzhacker stated that it was to Lula's credit that he recognized his own weakness and completely changed his style. She noted that Janones managed to do something that seemed unthinkable for Brazil's left, which was dominate social media.

Sociologist Mayra Goulart, a professor at the Federal University of Rio de Janeiro, also cautions against attributing the result solely to social media. She argues that Flávio Bolsonaro entered the run-off overly confident and failed to communicate his message effectively to supporters. Goulart describes the victory as a combination of social media and street-level mobilization. She believes the physical world enabled a form of mobilization capable of reducing abstention and persuading undecided voters.

Goulart says Lula's supporters worked to turn online enthusiasm into real-world political engagement. Those committed to the victory brought people together to persuade them to vote. She argues this effort helped increase turnout and converted a significant number of undecided voters. Goulart believes this collective effort was an important learning experience that will prove valuable for the next administration as it faces upcoming challenges.
