This replication package contains the cleaned Stata datasets and code needed to reproduce the main results of the article. The data combine public municipal election records from Brazil and Chile, with the candidate-election as the unit of observation. The analysis compares close electoral outcomes between the last winner and the first loser within the relevant electoral list: coalitions in Brazil and parties in Chile. The main variables identify the election year, running variable, seat-winning status, candidate gender, party ideology or coalition, and whether the candidate reran in a subsequent election. The Brazil data cover municipal elections in 2012, 2016, and 2020, with follow-up through 2024; the Chile data cover municipal elections from 1992 to 2012, with follow-up through 2016.
