The tight contest for first place in Rio Grande do Sul’s October 4 Senate election reflects a fragmented field where Marcel Van Hattem (Novo) and Manuela D’Ávila (PSOL) hold narrow leads in recent polling, followed closely by Ubiratã Sanderson (PL), Germano Rigotto (MDB), and Paulo Pimenta (PT). Multiple surveys through late August show these five candidates in technical ties when first and second preferences are combined, with high shares of undecided voters and low single-digit support for remaining contenders. The two-seat, single-round system amplifies small shifts in turnout or late movement among center-right and left-leaning blocs. Trader pricing captures this uncertainty, with no candidate exceeding 45% implied probability for topping the ballot. Scheduled debates and final campaign pushes in the coming weeks could consolidate preferences and widen gaps before voting.
