**Recent polling from Datafolha, Quaest, and AtlasIntel shows Marília Arraes (PDT) and Humberto Costa (PT) in a technical tie for the two Senate seats in Pernambuco, with Arraes often slightly ahead on first-choice votes and Costa competitive on combined or second-preference tallies.** This positioning stems from their joint alliance with João Campos (PSB) in the gubernatorial race, encouraging strategic split-ticket voting among left-leaning voters who prioritize both candidates. Mendonça Filho (PL) and Eduardo da Fonte (PP), backed by Governor Raquel Lyra’s PSD-led group, trail in third and fourth, limiting their chances for second place. The race remains tight due to high undecided shares, the dual-vote system, and minimal late shifts in the final surveys conducted October 2–3. Separation would likely require stronger turnout differentials or unexpected swings among centrist or right-leaning voters on election day.
