Brazil prepares for a tight runoff as Lula da Silva and Flavio Bolsonaro rally supporters ahead of Sunday’s vote, following a combative final debate. Lula led in the early round but has narrowed the gap amid fierce campaigning; Bolsonaro seeks to extend his father Jair Bolsonaro’s political legacy with hard-line security promises. The race carries implications for Brazil’s direction in regional politics and its stance on global issues such as deforestation, inflation, and relations with the US.
