Brazil has a big vote on Sunday. The people choose a new president. Two known men run against each other. One man is Luiz Inacio Lula da Silva. He is 80 years old. He is the current president. He wants to win again.
His rival is Flavio Bolsonaro. He is 45 years old. He is the son of former president Jair Bolsonaro. Jair Bolsonaro has house arrest. He must stay at home. His son Flavio wants to continue his politics.
Polls say: The race is very close. Nobody gets more than 50 percent of votes now. Then a second vote happens on October 25. The top 2 candidates run again then.
The election fight is very hard. Both sides argue a lot. The USA also helps. Donald Trump supports Flavio Bolsonaro. Lula da Silva says: Brazil decides alone. Millions of people must vote.
