Quaest: Almost three in ten voters would disapprove of their son marrying a political rival

After the presidential election, 28% of Brazilians say they would disapprove of their son or daughter marrying someone from the opposing political camp, according to a Quaest survey released this Monday (9).

The index rose ten percentage points compared to December 2025, when it was 18%. In December 2022, right after the dispute between Lula (PT) and Jair Bolsonaro (PL), it was 25%. The highest level in the series was in December 2024, with 32%.

This time, the question was adapted to the vote of each interviewee. Those who voted for Lula were asked about marriage with a Bolsonaro member, and those who voted for Flávio Bolsonaro (PL) were asked about marriage with a PT member.

Other signs of polarization in everyday life remain stable or declining. 29% prefer to watch a TV channel that thinks like them, practically the same as the 30% in December 2022. The peak was in December 2024, with 45%, and the question was not asked in the December survey last year.

The share of those who would change country if they could is also 29%. It is the lowest index in the series, tied with December 2021, the first year of the survey. At the end of 2022 it was 37%, and the number reached 43% in December 2024.

10% of those interviewed say they have broken relationships with family members because of politics, compared to 36% in December 2023.

Another 17% would stop listening to an artist who supported the opponent, and 9% would stop buying a brand in the same situation. In December 2024, the rates were 38% and 25%, respectively.

They would change churches if the religious leader supported the rival candidate 8%. A 6% share would remove the child from a school where the majority of parents support the opponent, an item that reached 34% in December 2024.

Quaest, hired by the newspaper O Globo, personally interviewed 2,004 voters between October 30th and November 2nd. The margin of error is two percentage points, and the confidence level is 95%.
