A poll by Quaest gave President Luiz Inacio Lula da Silva a narrow lead over Flavio Bolsonaro ahead of Brazil's October election, though the run-off margin sits inside the survey's own error bar, according to Al Jazeera's report on the poll [1].

In a simulated run-off, Lula drew 43 percent to Bolsonaro's 40 percent [1]. The poll's margin of error is two points, which means the three-point gap between the two men is not statistically distinguishable from a tie [1]. A first-round scenario showed a wider separation, with Lula at 38 percent and Bolsonaro at 31 percent [1].

Quaest surveyed 2,004 people between August 10 and 13, and the poll was commissioned by the Brazilian media group Globo [1].

The candidate here is not the more familiar Bolsonaro. Flavio Bolsonaro, the eldest son of former President Jair Bolsonaro, has become the standard-bearer for Brazil's right after his father was barred from running [1]. Al Jazeera reports the elder Bolsonaro was ruled ineligible after Brazil's top electoral court found he had abused his power in office, and that he was later convicted over a plot to overturn his 2022 election loss to Lula [1].

What the numbers actually support is narrow. A three-point edge inside a two-point margin of error describes a run-off that is, on this evidence, too close to call, while the same poll shows Lula with a clearer seven-point lead in the first round. One survey, taken over four days in August, is a snapshot of a race that does not vote until October, not a forecast of how it ends.
