The Latest: Brazilians vote in presidential election dominated by Lula and Bolsonaro

Brazilians are voting Sunday in a pivotal presidential election dominated by incumbent Luiz Inácio Lula da Silva and his ideological opposite, Sen. Flávio Bolsonaro.

Preelection polls suggested both have a chance of winning outright, but if neither gets a majority of the vote, a runoff will be held on Oct. 25.

Nearly 159 million Brazilians are eligible to vote in Latin America’s largest economy. Bolsonaro is an ally of U.S. President Donald Trump and the son of ex-leader Jair Bolsonaro, whom Lula defeated four years ago.

Here's the latest:

Alongside regional heavyweights like U.S. President Donald Trump and Nicaraguan President Daniel Ortega, 80-year-old Luiz Inácio Lula da Silva stands among the oldest leaders in the Americas.

If Lula achieves an outright victory against 45-year-old Flávio Bolsonaro, he will cement a historic milestone, becoming the oldest man ever elected to lead the South American nation.

He says he wants to live to be 120. He tried to ease concerns by posting workout videos to attempt to convince voters that age is just a number.

Voting has started in Brazil's high-stakes presidential election, pitting the two main candidates, incumbent Luiz Inácio Lula da Silva and his ideological opposite, Sen. Flávio Bolsonaro , against each other.

Almost 159 million Brazilians are eligible to vote in this tense political showdown.

Brazilians will also elect 27 state governors, members of state legislatures, all 513 federal members of the lower house of congress and 54 of the country’s 81 senators in Sunday’s vote.
