I examine the five nations where levels of democracy improved and runoff worked well. Runoff opened the political arena to new parties, enhanced presidential legitimacy, and/or enticed parties at extremes toward the center. The number of parties did not increase in the Dominican Republic, El Salvador, or Uruguay and, although the number of parties was large in Brazil and Chile, two broad coalitions formed for presidential elections. This chapter first contrasts the negative effects of plurality and the positive effects of runoff in the country that is a model for runoff advocates: Uruguay. Next, it shows the negative effects of plurality in another country that adopted runoff during the third wave: the Dominican Republic. Then, the chapter turns to Brazil and Chile, where the advantages of runoff for both legitimacy and the incorporation of the left were very evident. Finally, I turn to El Salvador, where until 2014 the advantages of runoff were least apparent.
