Flávio Bolsonaro's running-mate problem is the whole story

BRAZIL'S presidential race on October 4th should be a rematch. Incumbent President Luiz Inácio Lula da Silva is seeking a fourth term and will be paired once more with Vice-President Geraldo Alckmin, who he confirmed as his running mate in March. His opponent is Senator Flávio Bolsonaro, the eldest son of former President Jair Bolsonaro, who was formally nominated by the Liberal Party (PL) on July 25th. Yet there is a complication. Mr Bolsonaro does not yet have a vice-presidential candidate. The deadline to register a complete ticket is August 15th, and the choice may not be made until the eleventh hour.

The delay is not a scheduling oversight. It is a symptom of a deeper problem.

Brazil elects the president and vice-president as a joint ticket using a two-round system. A running mate is not an afterthought; the choice signals which parties, regions and voter blocs the presidential candidate can assemble. Mr Lula's early confirmation of Mr Alckmin, a former governor of São Paulo from a centrist party, projected stability and a broad coalition. Mr Bolsonaro's silence projects the opposite.

The structural cause is familiar. In Brazil's fragmented party system, a presidential ticket is less a manifesto than a map of political bargaining. Mr Bolsonaro's father built a winning coalition in 2018 and 2022 by attracting centrists, evangelical leaders and regional bosses. The son has failed to replicate the arrangement. The Republicans party, a potential ally, recently confirmed its neutrality, frustrating plans to recruit Daniella Marques, a former president of Caixa Econômica Federal (the state-owned development bank) and the coordinator of Mr Bolsonaro's economic platform. Her party insiders resisted: she had only recently joined and, as one member noted, other women had longer track records. The PL's convention minutes were deliberately drafted to authorise its executive committee to keep negotiating after the formal convention period - a legal workaround that acknowledges the absence of a ready partner.

Several names circulate. Pedro Lupion, a federal lawmaker from Paraná, has been mentioned. Marcos Pontes, a former astronaut turned senator for São Paulo, could help attract votes in Brazil's most populous state. A high-profile female candidate such as former Agriculture Minister Tereza Cristina was pursued but rejected - her Popular Party... has distanced itself. That is a starker snub than it sounds. Without the Popular Party, the PL's leverage in Congress is thinned before the election even begins.

The incentive structure is clear. Potential allies are waiting to see whether Mr Bolsonaro can win before committing. They can hold out for better terms, or simply position themselves to negotiate from strength should Lula lose. The result is a familiar one: the candidate who looks weakest attracts the fewest partners, which makes him look weaker still.

To be sure, the convention in São Paulo was not devoid of spectacle. Argentina's President Javier Milei appeared in person. A video endorsement from Israel's Prime Minister Benjamin Netanyahu was displayed. An AI-generated message from the elder Mr Bolsonaro, who is serving a 27-year sentence for plotting a coup after his 2022 defeat, was played to cheers from roughly 500 supporters. But international endorsements cannot replace domestic alliances. Mr Milei can declare "the Lula risk" a danger to Latin America's largest economy; he cannot deliver a single seat in the Chamber of Deputies or a swing state in the Midwest.

Meanwhile, Mr Bolsonaro's campaign has been consumed by self-inflicted crises. In May, he admitted to requesting millions of dollars from Daniel Vorcaro, a jailed disgraced banker, to fund a film about his father. A public spat with his stepmother, Michelle Bolsonaro - a leader among evangelical voters - cost him support among women and independents, even if a belated reconciliation was staged before the convention. And a Nexus/BTG Pactual poll published on August 3rd, covering the period from July 31st to August 2nd, showed Mr Bolsonaro's polling position deteriorating: in a simulated second-round runoff, Mr Lula leads 46% to 45%, a tightening from 47%-43% in late July and a reversal from April, when Mr Bolsonaro held the advantage.

The tariff fallout deserves mention. Mr Bolsonaro visited Washington expecting a boost from the Trump administration. Instead, Quaest polling indicates that more Brazilians blame him than Mr Lula for the 25% U.S. tariff on Brazilian exports levied in mid-July. A diplomatic trip intended to demonstrate influence ended up highlighting dependence.

The real question beneath the running-mate hunt is whether Bolsonarism can survive its founder behind bars. Jair Bolsonaro was convicted, stripped of eligibility for office until 2030, and placed under house arrest before being moved to pretrial detention. His movement now lacks a unifying figure, a coherent economic platform, and a credible coalition. Flávio Bolsonaro has proposed a 12-point security programme called Brasil sem Medo (Brazil without Fear), which includes declaring criminal groups "narcoterrorist organisations" and building maximum-security prisons modelled on El Salvador's system. He has not released a detailed economic plan, though he is expected to reduce spending and delay Brazil's tax reform. Amnesty for his father and those convicted in the January 8th 2023 storming of Brasília remains a stated aim. These are positions that energise a base but do not attract centrists.

The strongest counter-argument is that the vice-presidential choice may still salvage the ticket. A charismatic, well-connected figure - perhaps Mr Pontes, the astronaut - could broaden the coalition's appeal in the final weeks. Political consultant Thomas Traumann, based in Rio de Janeiro, has noted that Mr Bolsonaro has 'faced a problem each week, sometimes two', adding that the senator has said 'the campaign only starts in August'. There is a method to this deferral: wait until the last moment, when the arithmetic of alliances is clearer and potential partners are under more pressure to choose a side.

Yet the structural disadvantage remains. Mr Lula, 80, has the incumbency advantage, a confirmed running mate, and a party that controls the presidency. Mr Bolsonaro's campaign has been defined by what it has lost: centrist allies, evangelical loyalty, business confidence, and the aura of inevitability that once surrounded his father's brand. A late running mate can improve a ticket. It cannot rebuild a movement.

The danger for Brazil is not that Mr Bolsonaro wins. It is that the election deepens the country's institutional fractures. A narrow defeat, followed by claims of judicial persecution and electoral manipulation - themes the senator has already rehearsed - could leave Bolsonarism as a permanent source of destabilisation. A narrow victory would be worse.

The better answer is not to cheer Mr Lula's probable re-election. It is to observe that the right's failure to produce a credible, coalition-ready candidate reveals a vacancy in Brazil's political architecture. Parties that prefer ideological purity to institutional seriousness will find that neither wins elections nor governs well. The cost will not fall evenly. It will fall on the institutions - courts, electoral bodies, the armed forces - that are asked to absorb the fallout. Those are the institutions Brazilians should be watching most closely.
