Improved Approval Runoff is a trying to fix Two-round runoff, to avoid cases like 2002 French presidential election. You can approve your favourite candidate with low chances of winning, and other satisfactory frontrunner. In Rio de Janeiro mayor election of this year, for example,the polls revealed than the 1st candidate was Eduardo Paes, a centrist, and the 2nd was Marcelo Crivella, a conservative protestant politician. The leftist votes were splitted between Fernando Gabeira (Green party) and Jandira Feghali (Communist Party). On the election day, many voters of Feghali changed their votes for Gabeira, an espontaneous compromise strategy (in Brazil we call this strategy as "voto útil = useful vote"). The result is that Paes and Gabeira will contest the runoff. If Rio election was conducted using Improved Approval Runoff, Feghali`s supporters were be able to approve both Feghali and Gabeira. -- ________________________________ Diego Renato dos Santos
