SAO PAULO, Oct 3 (Reuters) – Brazilian President Luiz Inacio Lula da Silva’s lead over Senator Flavio Bolsonaro narrowed ahead ​of Sunday’s first-round vote, a CNT/MDA ‌poll showed on Saturday, while also pointing to a tighter race in a likely runoff.

In a first-round scenario, Lula would receive 43.1% of voter support, ‌followed ​by Bolsonaro (38%), Augusto Cury (3.2%), Ronaldo ⁠Caiado (3%) and Renan ⁠Santos (1.5%), according to the poll.

• A September 15 poll had Lula at 40.5%, Bolsonaro at 30.4%, Cury at 6%, Caiado at ​3% and Santos at 2.7%

• Considering only projected valid votes, which exclude people ⁠telling the pollster they ⁠would leave their ballots blank or ​void somehow, Lula reached 47.8% voter support against ​Bolsonaro’s 42.1%

• If no candidate wins ‌more than 50% of valid votes in the Sunday first round, the two frontrunners advance to a runoff on October 25

• In ⁠a likely runoff, Lula would receive 47.3% of voter support, compared with 43.1% for the eldest ⁠son of ‌former President Jair Bolsonaro, the ⁠poll said

• In the previous survey, ​Lula ‌led Senator Bolsonaro by 47.3% ​to 40% ⁠in the runoff

• MDA surveyed 2,007 people from September 30 to October 2, with a margin of error of 2.2 percentage points
