The first rounds of the general elections in Brazil take place this Sunday, and voters are expected to elect the new President of the Republic, the governors, and the deputies that will make up the federal and state legislative houses.

For these elections a greater contest at the polls is expected between the current Head of State, Jair Bolsonaro, and the former Brazilian president, Lula da Silva.

Polls released in the last week before the election indicate the possibility of a victory for Lula da Silva, who has about 48% of voting intentions and Bolsonaro with the support of about 36%, in the first round if Lula manages to reach 50% of the valid votes plus one.

However, variables such as abstention and the undecided vote could lead to a second round on October 30.

Besides these two figures, the Brazilian presidential candidates are Ciro Gomes, Simone Tebet, Luís Felipe D'Ávila, Soraya Tronicke, Eymael, Padre Kelmon, Leonardo Pericles, Sofia Manzano, and Vera Lúcia.

In these general elections, for the first time all of Brazil's polling stations will operate from 8 a.m. to 5 p.m. in Brasília, the country's capital, which will force cities located in different time zones to adjust their voting hours.

In this ballot, the governments of the 27 states of the country are also at stake, in disputes led by very diverse candidates, and the regional elections can either be decided in the first round if a candidate reaches more than 50% of the votes in the states, or end on October 30 when the second round of elections for executive positions takes place.
