The coalition, with Mariano Ricalde as its candidate, seeks to elect a city government with progressive policies in line with those of the Fernandez administration. Elections will be held July 5 and if no candidate gains a majority, a second round of voting will be held. Laureano Ponce reports from Buenos Aires. teleSUR.
