Articulações Intrapartidárias e Desempenho Eleitoral no Brasil

Do Brazils political parties matter in elections? The article focuses on this problem by analyzing whether a mayors election influences his partys electoral performance in the same city. A regression discontinuity model (RDM) was used to identify the causal effect of mayors on their partys electoral performance in elections to National and State Deputies. The findings suggest that a mayors election (even by a difference of only 1%) should increase the votes for the same party in the elections to both National and State Deputy. This result is interpreted as evidence of intra-partisan linkage, whereby mayors act systematically to help elect National and State Deputies from their own parties
