SAN SALVADOR (Reuters) - A former guerrilla commander hopes to keep his left-wing party in power in El Salvador's presidential election on Sunday, but he faces a strong challenge from a right-wing rival who wants to use the army to battle powerful street gangs.
Polls give Vice President Salvador Sanchez Ceren of the leftist Farabundo Marti National Liberation Front, or FMLN, an edge over his conservative adversary Norman Quijano, who stepped down from a second term as mayor of San Salvador to run.
