Recent polling in Pernambuco's Senate race shows Marília Arraes (PDT) maintaining a clear lead for first place, while Mendonça Filho (PL) and incumbent Humberto Costa (PT) remain locked in a tight contest for second, with the former holding a narrow edge in the latest Real Time Big Data survey at 20% to 19%. Eduardo da Fonte (PP) and Túlio Gadêlha (PSD) trail further back. High undecided and blank/null shares, exceeding 25% in multiple surveys, sustain volatility ahead of the October 4 vote. Mendonça's recent gains align with bolsonarista endorsements and right-leaning consolidation, while Costa benefits from PT organizational support and the Arraes alliance. These dynamics keep second-place probabilities closely matched, with final voter turnout and late shifts among undecideds likely to determine separation.
