Brazil Presidential Election

What this question means

Fifty-two to forty-six. Luiz Inácio Lula da Silva and Flávio Bolsonaro are separated by six points, with Jair Bolsonaro at 3% and the rest of a seventeen-name field at 2% or below.

A margin this narrow between two candidates is as close as electoral questions get. For practical purposes the crowd is saying this is a coin flip with a slight lean, and that the outcome will be decided by factors — turnout, late movement, campaign events — that cannot be forecast in advance.

Brazil uses a two-round system, which shapes the numbers. A candidate needs an outright majority to win in the first round, otherwise the top two advance to a runoff. That structure tends to consolidate support around two names as the date approaches, which is visible here in how little probability the rest of the field retains.

Resolves 4 October, so most of the deciding information is already in.
