Since the adoption of the two-round system in Brazilian elections with the 1988 Constitution, winning in the 1st round requires an absolute majority (50% + 1 of the valid votes). In São Paulo, only José Serra (2006) and Geraldo Alckmin (2010, 2014) had achieved this by 2026, all from the PSDB. Tarcísio de Freitas broke this pattern by being re-elected in the 1st round in 2026.

Tarcísio de Freitas (Republicans) was re-elected governor of São Paulo this Sunday (4), in the 1st round of elections, with 62.85% of valid votes, against 36.22% for Haddad. The result was confirmed at 7:39 pm, with 90% of the ballots counted by the Regional Electoral Court (TRE).
It is the fourth time that a São Paulo governor has been elected in the 1st round since the adoption of the two-round system in 1990. In 2022, he also defeated Haddad, but in the 2nd round.
Until this Sunday, all governors elected for the first time were from the PSDB: José Serra in 2006 and Geraldo Alckmin in the 2010 and 2014 elections. Tarcísio is the first from another party to achieve the feat.
The concept of "winning in the 1st round" only formally came into existence in Brazil after the 1988 Constitution. The text establishes that:
For the positions of president of the Republic, state governors and mayors of municipalities with more than 200 thousand voters, the winning candidate must obtain an absolute majority;
In other words, 50% plus one of the valid votes, not counting blank and null votes;
If no one reaches the mark, the two most voted will face each other in the 2nd round.
Before this rule, Brazilian elections for the Executive operated in a single round, with a simple majority, whoever had the most votes won, regardless of reaching 50%. This is how, for example, Franco Montoro (PMDB) won the election in 1982, the first direct contest for the São Paulo government since the 1960s.
History of victories in the 1st round
1) 2006 election: José Serra (PSDB)
Valid votes: 57.93% (12.3 million votes)
In 2006, the toucan made history by becoming the first governor elected in the 1st round in São Paulo under the 1988 Constitution. Serra had considerable approval from his management at São Paulo City Hall. The defeated candidate was Aloizio Mercadante (PT), who received 31.68%. Third place was former governor Orestes Quércia (PMDB), with 4.57%
2) 2010 election: the return of Geraldo Alckmin (PSDB)
Valid votes: 50.63% (11.5 million votes)
Four years after Serra's feat, the PSDB repeated the feat with Alckmin, who had already governed the state between 2001 and 2006. The main opponent was, again, Mercadante, who ended the dispute with 35.23%. Celso Russomanno (PP) came in third, with 5.42%.
3) 2014 election: Alckmin again
Valid votes: 57.31% (12.2 million votes)
Amidst a scenario of popular dissatisfaction motivated by the 2013 water protests, Alckmin entered the year of re-election with an approval rating hovering around 40%. This helped to establish a wide gap to second place, Paulo Skaf (PMDB), who had 21.53% of the votes. Alexandre Padilha (PT) obtained 18.22%.
4) 2026 election: Tarcísio re-elected
Valid votes: 62.85%% (13,057,319 votes) - updating
Upon being re-elected, Tarcísio became the first name without PSDB affiliation to win the São Paulo government in the first place. Four years ago, in 2022, when he was a candidate for the São Paulo government for the first time, he needed to go to the 2nd round to defeat Haddad. The PT member won 44.73% of the valid votes, against 55.27% for the current governor.
This time, however, with the public machine in hand and 47% approval from management, Tarcísio managed to end the dispute this Sunday.
