Brazil Senate race in SP tight: four candidates within margin of error

A Vox Brasil poll shows four candidates statistically tied for Brazil's São Paulo Senate seat, with Derrite at 28.2%, André at 26.6%, Marina at 25.9%, and Tebet at 23.1%, within a 2.55 p.p. margin. The race is highly competitive and could shift with late momentum. This matters as the Senate balance of power in Brazil may hinge on this key state.
