Mário Covas, who passed away 25 years ago, played a pivotal role in shaping the principles of the PSDB party in Brazil, encapsulated in the 'Manifesto ao Povo Brasileiro' released in 1988. This manifesto was indicative of a social-democratic platform that sought to blend social justice with support for private initiative, corresponding to the country's redemocratization efforts. His leadership saw the PSDB rise to prominence during Fernando Henrique Cardoso's government from 1995 to 2002, a time when the party was a significant player in Brazilian politics.

However, in recent years, the PSDB has struggled with its identity and relevance, as noted by scholars and former allies of Covas. They argue that the party has not only failed to renew its leadership but has also absorbed an anti-political mindset, leading to a significant decrease in its members and overall influence. This loss of identity is a stark contrast to the era of Covas, who was deeply committed to the ideals of social democracy and was characterized by an engaging and devoted political style.

The reflection on Covas's legacy emphasizes the current political challenges faced by the PSDB and serves as a critical reminder for the party to reassess its role and principles in contemporary Brazilian politics. Covas's vision of a just society is a poignant benchmark as the party grapples with redefining itself in a changing political landscape, which has seen emerging parties and ideologies taking the forefront.
