Brazil's Independence Day on 7 September became a stage for rival political forces as the country heads into a presidential election just weeks away, with the latest polling showing the race narrowing to a near-statistical tie. A Quaest poll places incumbent President Luiz Inácio Lula da Silva of the left-wing Workers' Party (PT) at 42 percent in a potential second round, down slightly from 43, while his main challenger, Senator Flávio Bolsonaro of the right-wing Liberal Party (PL), has edged up to 41 percent from 40. With the first round fewer than 30 days away, Brazil's September 7 holiday — long a flashpoint for political mobilisation — once again served as a barometer of the country's deep divisions.

The two campaigns held contrasting events. In Brasília, Lula attended the official civic-military parade on the Esplanada dos Ministérios, obeying strict electoral rules set by the Superior Electoral Court (TSE) that prohibited campaign materials and overt electioneering. He did not speak from the stage, having delivered an institutional address the previous day with TSE clearance, and instead acknowledged the chanting crowds with a heart gesture. His social media posts afterwards emphasised national sovereignty, taking implicit aim at foreign influence without naming specific actors.

In São Paulo, Flávio Bolsonaro and his allies held a rally on Avenida Paulista — one of the city's most iconic boulevards — where speeches centred on Supreme Court Justice Alexandre de Moraes, the ongoing Banco Master financial scandal, and the January 8, 2021 riot convictions, for which Jair Bolsonaro, Flávio's father and former president, is currently imprisoned. Speakers were notably more measured than in previous years, carefully distinguishing between the Supreme Court as an institution and Moraes as an individual, apparently wary of running afoul of tightened electoral regulations. "A rotten orange cannot contaminate the whole court. The STF is not Alexandre de Moraes," Flávio Bolsonaro told the crowd.

The institutional backdrop adds considerable complexity to the campaign. A bitter public dispute between two Supreme Court justices, André Mendonça and Alexandre de Moraes, intersects with the Banco Master scandal and has deepened already widespread mistrust of Brazil's courts. Analysts caution, however, that institutional controversies may not be the decisive factor. According to Andreza Aruska de Souza Santos, director of the King's Brazil Institute at King's College London, the gap between Brazil's relatively solid macroeconomic headline figures and the harsher daily reality experienced by many citizens — shaped by the cost of living and a volatile job market — could prove more electorally consequential than any individual controversy.

With the race effectively tied, both campaigns face a messaging challenge in the final stretch. Aruska also warns against assuming that external pressure from Washington will benefit Brazil's right, noting that appeals to national sovereignty can cut across ideological lines. In a country as polarised as Brazil, the election may ultimately be decided less by economic data than by how voters feel that data in their everyday lives.
