🗳 Election Observatory: Aug. 4

— by Paulo Abrão, executive director of the Washington Brazil Office

The week of party conventions set the shape of Brazil's presidential election. Lula, Flávio Bolsonaro, Ronaldo Caiado, Romeu Zema and Renan Santos were formally chosen by their parties, consolidating a contest that pairs government-versus-Bolsonaro polarization with candidacies competing for alternative space on the right. Smaller parties, mostly on the left, will add names, but the main forces are now in place.

Each convention pitched its own narrative. The Liberal Party confirmed Flávio Bolsonaro as his father's heir and exposed the limits of that succession: no other party joined his coalition, the ticket is still unfinished and the main center-right parties chose to keep their autonomy. Argentine President Javier Milei's prominence reinforced the far right's international ties, drew diplomatic friction and at times overshadowed the candidate. 

Flávio inherited Bolsonaro's electorate and symbolism, not his ability to assemble alliances. His challenge is to reach beyond his father's most loyal voters; his weakness is political isolation, compounded by the Banco Master fallout and by a broader exposure to investigations that leaves the candidacy unusually vulnerable to developments no one can yet see.

The Workers' Party convention was marked by progressive unity around Lula and by the decision to keep Geraldo Alckmin on the ticket. In his seventh presidential campaign, Lula framed the election as a defense of national sovereignty, democratic institutions and his administration's social policies. That unity sits alongside an unanswered question: whether the left can build a succession beyond Lula himself. 

His challenge is converting economic and social results into something voters feel day to day. His weaknesses are accumulated rejection, the difficulty of renewing the progressive camp and the investigation into his son, Fábio Luís Lula da Silva, known as Lulinha. The allegations of influence peddling and corruption remain unproven, his defense disputes them and Lula has said his son should answer to the investigation without privileged treatment.

The Social Democratic Party confirmed Ronaldo Caiado alongside Gilberto Kassab, a ticket built on executive experience, party machinery and a conservative identity not subordinated to Bolsonarismo. His launch made the case for breaking the Lula-Bolsonaro binary from the right, with more institutional experience and greater capacity to negotiate. The challenge is turning the PSD's nationwide footprint into actual votes; the weakness is low national visibility against opponents with stronger name recognition.

The Novo confirmed Romeu Zema and tied his candidacy to fiscal responsibility, economic liberalism and his record in Minas Gerais. He competes with Flávio and Caiado for the same conservative voters and must show that a regional, party-based identity can scale. His challenge is nationalizing a trajectory strongly identified with Minas; his weakness is a limited ability to build alliances beyond the liberal-conservative electorate already close to the party.

Renan Santos and the Mission Party opened the convention season with a bid to represent a non-Bolsonaro right, built on the Free Brazil Movement. Public security dominated his convention, along with threats the candidate says he received from criminal organizations.

The campaign combines the fight against organized crime, criticism of traditional politics and a message of generational renewal. His challenge is converting digital reach and ideological activism into votes; his weaknesses are a thin party structure, little television time and limited appeal outside highly politicized circles.

The female vote will decide an election still dominated by male candidacies. Women make up the majority of Brazil's electorate yet remain underrepresented in positions of power and absent from the main tickets.

How each campaign handles income, caregiving, health, public safety, violence against women, reproductive rights, and equal opportunity matters. The test is whether any of them can move past generic messaging and engage the social, regional and generational diversity of Brazilian women.

Several questions are still open. Smaller parties have until August 5 to close their conventions, confirm candidates, form alliances or drop names floated during the pre-campaign. Some running mates and coalition arrangements remain undefined. Parties and coalitions must file registration requests with the Electoral Court by August 15. Campaigning is authorized from August 16, the first round falls on October 4, and any runoff on October 25.

One uncertainty cuts across every candidacy: how far international actors will involve themselves. Expectations of political, communications and digital support for Flávio Bolsonaro from the Trump administration and leaders of the global far right have fueled concerns about attempts to sway Brazilian opinion, delegitimize electoral institutions or pre-build arguments to contest a defeat.

Foreign backing for a candidate is not, in itself, unlawful interference; the line falls where foreign governments or networks pressure institutions, manipulate public debate, or condition recognition of the result in advance. Recent tensions with the US and Milei's active role at the Liberal Party convention suggest the international dimension will not stay peripheral.

The conventions produced an election with two dominant poles but not one confined to them. Lula starts with a broad, unified coalition, exposed to the wear of governing and to investigations touching his family. Flávio Bolsonaro has a substantial social base and international backing, but enters isolated and vulnerable to fresh controversy.

Caiado, Zema and Renan are betting there is room for a third option. With the selection process largely settled, the question is no longer who runs, but which candidacies can complete their tickets, survive crises, win the female vote, absorb surprises and keep the process legitimate under domestic and international pressure.

Journalism and democracy are inseparable — and right now, both are under threat. A free press is not a luxury; it is the infrastructure of accountable governance, and when it weakens, so does everything else. That is why your support matters.

Every four years, the loose bloc of parties known as the Big Center, or centrão, becomes the belle of the ball, courted by candidates on the left and the right. It also explains much of why governing Brazil is so hard.

The name misleads. The Big Center is not a caucus of moderates but a coalition of conservative forces, born in the 1987-88 Constitutional Assembly to block what its founders saw as a left-wing wave that would saddle a young democracy with an unaffordable welfare state. Its members are pragmatists rather than ideologues, willing to deal with any president in exchange for pork. Most backed Luiz Inácio Lula da Silva during his first terms and, years later, the far-right Jair Bolsonaro with equal ease.

The bloc's leverage is arithmetic. Dominance in city halls and large benches in Congress make these parties unavoidable for anyone trying to pass legislation, Eduardo Grin, a political scientist at the Getulio Vargas Foundation's School of Public Administration (FGV-EAESP), told this observatory.

In 2026, the Big Center has largely stayed neutral between Lula and Senator Flávio Bolsonaro, knowing either winner will need it to govern. That is less about ideology, Grin said, than about keeping options open in a tight race. The stance has frustrated the Bolsonaro camp, which counted on the bloc's most conservative fringes to build a coalition. But for the Big Center, fence-sitting is the surest way to keep power.

One day before the August 5 convention deadline, Flávio Bolsonaro still has no running mate. Senator Tereza Cristina was Flávio's preferred running mate, but her party blocked her. The Progressives, a Big Center mainstay, declared neutrality and refused to convene, keeping its state directorates free to back Flávio where the right is strong and Lula where the left is.

Flávio said Sunday night he was also talking to the Republicans. Economist Daniella Marques is the name circulating there, though that party, too, is expected to remain neutral.

Flávio wants a woman on the ticket to shore up his weakest constituency, female voters. Not having one on the eve of the deadline exposes how thin his alliances are.

Romeu Zema, the candidate for the libertarian Novo party, is in a similar bind. He has yet to announce a VP nomination and is courting Podemos, which is also in the Big Center. If no one accepts by August 5, he may have to pick from his own party.

Parties have until August 15 to formally register their candidates. Two national conventions are still pending: the Republicans' convention on August 4 and the Workers' Cause Party (PCO) Convention on August 8.

Supreme Court Justice André Mendonça has authorized two investigations into President Lula's eldest son on suspicion of influence peddling. The Federal Police are examining whether Fábio Luís Lula da Silva, known as Lulinha, pressured public institutions to favor businessmen linked to a pension-fraud inquiry. Corruption and money laundering are also under investigation. His lawyers deny any wrongdoing and have asked for an investigation into what they call criminal leaks intended to hurt his father's re-election campaign. This week, the Federal Police asked for authorization to open a third investigation into Lulinha.

Every poll points to a 2026 race decided between President Lula and Senator Flávio Bolsonaro. Lula is the only left-wing candidate who matters; the rest come from minor parties with no path to office. Flávio faces a crowded conservative field, but his floor is high enough that no rival looks likely to displace him in a probable runoff. One candidate is trying to break that duopoly anyway — if not in 2026, then in 2030.

Renan Santos, of the newly created Mission party, runs on the exhaustion with the political system that pervades Brazilian life. The 42-year-old is in some respects more radical than the Bolsonaros. His platform borrows from Nayib Bukele, El Salvador's president, and from Curtis Yarvin, the American neoreactionary writer who argues democracy is obsolete and should be replaced by a chief-executive-style ruler.

The candidacy is a long-term project, and not needing to win this year buys Santos a luxury no other conservative has: he can attack Flávio Bolsonaro (and he does so with gusto). That alienates the hard-core Bolsonarista base, roughly 25-30% of the electorate, but it lets him claim ground on the right untethered from the polarization Lula and the Bolsonaros have defined.

Polls put him far behind the two front-runners, though some place him ahead of the former governors Romeu Zema and Ronaldo Caiado. These are mostly online surveys, which tend to screen out less engaged voters — but Santos is a name that will outlast this campaign.
