On Oct. 25, the people of Latin America’s largest democracy and economy will vote in a presidential runoff. Neither the conservative candidate, Sen. Flavio Bolsonaro, nor the socialist incumbent, Luiz Inacio Lula da Silva (known as Lula), secured an outright majority in the first round of voting.

Bolsonaro is the favorite. Recent polls show him with a narrow but consistent lead, with 51% support.
