This paper aims to discuss how the introduction of a limited vote can benefit the achievement of efficiency in Brazilian legislative elections. The Brazilian experience with proportional voting has districts of high magnitude and a significant number of candidates, making it difficult for candidates and voters to act. We argue that if the voter had, instead of a single vote, a greater number of choices, second and third preferences could be captured, in the context of countless candidacies. Specifically, we point out, based on results in the literature, that making up to three votes available, in districts that are at least eight candidates, would increase the efficiency of public choices of legislative representatives.
