Norman Quijano. The mayor of San Salvador from the ARENA party won a second term by a landslide. As mayor of the country's largest city, he has already shown the ability to gather significant support and is probably viewed as someone able to get things done.
Tony Saca. President of El Salvador from 2004-2009, Tony Saca is rumored to be interested in returning to the presidency. The ARENA party elected him, but now they call him a traitor because of his connections to the breakaway GANA party. He is now the leading figure to be a presidential candidate for GANA. (A president in El Salvador may not be re-elected to successive terms, but can be re-elected when there is a gap in time between the presidential terms).
Salvador Sanchez Ceren. The current vice-president of El Salvador and former guerrilla commander is one of the traditional hard-left leaders of the FMLN. According to ContraPunto, the FMLN leadership is lining up to choose Sanchez Ceren as its candidate for 2014. The party leadership is unhappy with Mauricio Funes who they believe has not been true to the party agenda. In the same ContraPunto article, Mauricio Funes is quoted expressing skepticism about Sanchez Ceren as a candidate rather than a moderate leftist like Funes.
The FMLN, as well as the other parties, might do well to look at the example of Funes. His popularity remains high, as shown by a recent Mitofsky poll giving Funes a 65% approval rating - the highest in Central America.
