Daniel Scioli, candidate of the ruling left-of-center Front for Victory in Sunday's Argentine presidential elections, surged ahead in opinion polls, with more than 40 voter support and 10 above his closest rival. If the opinion poll numbers are ratified at the ballot box, there will be no need for a second round of voting. Scioli pledged that, if elected, he would exempt those earning under US$3,100 a month from paying income tax. His closest rival, Mauricio Macri, is running on a neoliberal platform.
