Brazil’s Divided Right Struggles to Unite Against Lula for 2026
Brazil · Politics
Key Facts
—The pick. Ronaldo Caiado, a right-wing presidential hopeful, named party boss Gilberto Kassab as his running mate on July 1 in Brasília.
—The shape. Both are on the PSD ticket, making it an all-in-house ticket rather than a broader alliance; Caiado previously belonged to União Brasil.
—The standing. Caiado polls at about 3% to 4%, contesting third place in a crowded centre-right lane.
—The front-runners. A BTG/Nexus poll in late June put Lula at 42% and Flávio Bolsonaro at 34%; subsequent July polls showed Lula at 40% and Flávio at 34% in the first round.
—The fixer. Kassab is a former São Paulo mayor and one of Brazil’s most influential congressional dealmakers.
—The vote. Brazil’s first round is set for October 4, 2026.
Brazil’s fractured right is struggling to unite behind a single challenger to President Lula, and its latest stumble is a running-mate pick one hopeful could not turn into the broad alliance he wanted.
Ronaldo Caiado, a right-wing former governor of the farm state of Goiás and one of several would-be challengers to President Lula, confirmed his number two on Wednesday in Brasília. The pick is Gilberto Kassab, the national chief of their shared party, the PSD.
On paper it is a routine step in a campaign. In practice it is a signal about the state of the opposition, and it matters to anyone trying to read where Brazilian policy heads after October.
Why the Caiado running mate choice is a compromise
The PSD had wanted an outside partner. For weeks the party courted União Brasil and the PP, hoping a second party on the ticket would bring more free television time and a bigger share of the public campaign fund.
Talks with the Novo party’s Romeu Zema also went nowhere. Neither man would agree to run as the other’s deputy, so the plan to merge two weak centre-right bids collapsed.
The result is what Brazilians call a “pure-blood” ticket, both names from the same party. It is a fallback, not the alliance the campaign originally wanted.
Kassab’s job is to fix a problem closer to home. As national party boss he is meant to pull the PSD’s scattered state branches behind Caiado, many of which back rival candidates today.
What the Caiado running mate move says about the race
The PSD is a party at war with itself. In Bahia it aligns with Lula under Senator Otto Alencar, while in the south some of its leaders lean toward Flávio Bolsonaro.
That split is the whole difficulty. A party pulled in three directions cannot easily throw its full weight behind one presidential bid, which is exactly the gap Kassab is being asked to close.
The national picture explains the stakes. A BTG/Nexus poll in late June put President Lula at forty-two percent and Senator Flávio Bolsonaro at thirty-four; subsequent July polls showed Lula at 40% and Flávio at 34% in the first round, with Caiado still stuck in low single digits.
Caiado is not a fringe figure at home. A physician and rancher, he governed the farm state of Goiás and swept all of its municipalities in his 2022 re-election, giving him a solid agribusiness base.
The trouble is turning that into a national vote. He shares the centre-right lane with Zema and others, in a field where analysts say Brazil’s traditional political centre has all but vanished.
His real bet is on the runoff, not the first round. Caiado hopes to be the moderate right’s fallback if the Bolsonaro brand falters, or a kingmaker who can swing his support late in the campaign.
Why the Caiado running mate matters to investors
For the foreign investor, the value is not in Caiado’s poll numbers. It is in what the ticket reveals about whether the right can converge on one candidate, the single variable that most shapes Lula’s re-election odds.
A splintered first-round right helps the incumbent. Every extra centre-right name draws votes that a unified opposition would need to force a competitive second round.
The opposition’s own bet is that this splintering is temporary. Rivals point to Chile’s 2025 election, where a divided right lost the first round but rallied behind one candidate to win the runoff. Our reporting has shown, however, that this Chilean model is far from guaranteed in Brazil; key figures like Romeu Zema have explicitly rejected the vice-presidential slot and are betting on a fragmented first round, a strategy that risks repeating the opposition’s failure to consolidate early rather than the Chilean success story.
Caiado has staked out market-friendly ground. He has floated privatising parts of Petrobras and signed a minerals-cooperation deal with Washington, positions that give him a distinct economic profile even at three percent.
The takeaway is about governability, not one man’s chances. How and when the fragmented right lines up will move the real, the Selic rate and Brazilian equities long before the October vote decides anything.
