Milei's Support for Bolsonaro Boosts Lula's Poll Numbers Amid Argentina-Brazil Crisis

On August 10, 2026, a Genial/Quaest poll showed that Argentine President Javier Milei's support for Brazilian politician Flávio Bolsonaro increased the likelihood of Brazilians voting for Luiz Inácio Lula da Silva to 34%. Meanwhile, the diplomatic crisis between Argentina and Brazil escalated as Argentina's ambassador to Brazil was recalled to Buenos Aires following new attacks by Milei. Milei also exchanged insults with a critic over a criminal complaint against Economy Minister Luis Caputo, while his sister Karina Milei urged the libertarian party to focus on building support to challenge Peronism.
