On a hot and sticky Sunday morning, pilgrims pour into the crypt of San Salvador Cathedral to pray at the tomb of Archbishop Oscar A. Romero. Grown men and women approach the tomb on their knees, whispering, “reza por mi” (pray for me). The pious scene may strike visitors as unremarkable for a Catholic country, yet there is deeper significance here: It is an election year, and the pilgrims are predominantly leftists.
