The Partido Social Democrático (PSD) officially nominated Ronaldo Caiado for president and Gilberto Kassab for vice president on Sunday, July 26, 2026 [1].

The move establishes a distinct right-wing alternative to the candidates of the Workers' Party (PT). By running a "chapa pura" — or pure ticket — the PSD is attempting to maximize its own political space in the upcoming election without relying on national alliances [2].

The official announcement took place during a national convention held in São Paulo [3]. The ticket pairs Caiado, the former governor of Goiás, with Kassab, who serves as the president of the PSD [2].

Party leadership intends to center the campaign on public security priorities [2]. The PSD is positioning itself as a corrective to current governance, offering a platform based on criticism of the PT and its leadership [3].

While some reports earlier this month suggested a different timeline for the vice-presidential announcement, the party finalized the pairing during the July 26 convention [1]. This strategic alignment signals the party's intent to challenge the existing political divide by presenting a consolidated front under a single party banner [2].

The convention served as the formal launch for the campaign, marking the transition from internal deliberation to a public bid for the presidency [3].

The PSD officially nominated Ronaldo Caiado for president and Gilberto Kassab for vice president.

The decision to run a 'pure ticket' indicates that the PSD is betting on its own internal brand strength rather than forming a broad coalition. By focusing on public security and opposing the PT, the Caiado-Kassab ticket aims to capture conservative and centrist voters who are seeking an alternative to the traditional political poles in Brazil.
