Lula and Flávio Bolsonaro approach Brazil's presidential vote

Multiple outlets identify Sunday's election and the principal rivals, while polling and campaign warnings need more scrutiny.

Brazil is preparing to vote on Sunday, with President Luiz Inácio Lula da Silva facing Flávio Bolsonaro. Al Jazeera and the Guardian describe a large Lula rally in Rio de Janeiro, while France 24 reports a neck-and-neck contest. Guardian coverage also describes a dispute involving Brazil's patron saint and the attorney general's warning against foreign meddling following its reporting on Trump administration funding plans.

What holds up

  • ✓NPR, the Guardian and France 24 identify Bolsonaro's son as Lula's opponent.
  • ✓Several items establish Sunday's vote and the closing campaign; Al Jazeera and the Guardian report Lula's Rio rally.

What doesn't yet
