Almirante relies on people aligned with Rio and former advisers to Costa and Sócrates. The PS (Socialist Party) is discreetly backing Seguro. Mendes is being boosted by the orange machine. Cotrim has help from IL (Liberal Initiative), and Ventura's one-man show continues.

Context & Explainers
- Leader: Mariana Leitão (since July 2025)
- Ideology: Classical liberalism, economic libertarianism
Founded in 2017, the Liberal Initiative advocates for reduced state intervention, tax simplification, labor market liberalization, and secular liberalism under the motto "Less State, More Freedom". The party gained its first parliamentary seat in 2019 and now holds 9 seats. Mariana Leitão, 42, became the party's first female leader in July 2025 after Rui Rocha resigned following disappointing 2025 election results. Leitão previously served as parliamentary leader and has been announced as the party's candidate for the 2026 presidential election. The party explicitly rejects alliances with both far-left and far-right parties, positioning itself as the "only alternative" that won't negotiate with extremes.
Socialist Party (PS)
- Leader: José Luís Carneiro (since June 2025)
- Ideology: Center-left, Social democracy, pro-Europeanism
Portugal's other traditional major party suffered a historic collapse in the 2025 election, dropping from 78 to 58 seats and falling to third place for the first time in democratic history. The party was led by Pedro Nuno Santos from January 2024 until his resignation following the May 2025 defeat. José Luís Carneiro, a 53-year-old former Minister of Internal Administration known for his moderate positioning within the party, was elected unopposed as the new Secretary-General with 95% of votes in June 2025. The Socialist Party governed Portugal from 2015 to 2024, including an absolute majority from 2022 to 2024 under António Costa, who resigned in November 2023 amid a corruption investigation. The PS previously led the innovative "Geringonça" (contraption) coalition government from 2015-2019, a minority government supported by the Left Bloc and Portuguese Communist Party that reversed austerity measures and presided over economic recovery.
