A Guide to 2018 Latin American Elections: Brazil



On October 7, 2018, more than 147 million people will vote for executive and legislature branches at the state and federal levels, choosing the following:

  • One president
  • 27 governors
  • 54 senators, corresponding to two thirds of the 81-seats Senate
  • 513 federal deputies
  • 1,059 state deputies

On October 28, there will be a runoff for president and governors in cases where winning candidates fail to snag 50 percent of votes. Federal and state deputies are elected based on a numerical proportion of votes given to candidates or parties, as well as on states’ population size. 

Between the arrest of a frontrunner candidate and with all major parties involved in the largest corruption scandal in Latin America, Brazil faces a volatile political scenario.
