Presidential candidate from the Avante party Augusto Cury received 11% of voter support in the first round, according to a BTG/Nexus poll released on Monday (31). The writer and psychiatrist improved his result by nine percentage points compared to the previous poll, in which he had 2%.
The institute analyzed two first-round scenarios — one including the candidacy of influencer Pablo Marçal (PRTB) and one without him. Both scenarios were presented in both the previous poll, released last Monday (24), and the new one. Cury achieved the same result in both versions — 2% last week and 11% this week.
