PLN's primary was more focus on personal attacks. In it José María Figueres Olsen, son of PLN's caudillo and former president José Figueres Ferrer, faced popular anti-corruption and anti-narcotraffic deputy José Miguel Corrales, alongside other candidates like former First LadyMargarita Penón (wife of Óscar Arias) and San José MayorRolando Araya (nephew of former president Luis Alberto Monge). Thus, most candidates except Corrales came from important political families. Figueres' image was affected by the "Chemise Case", the allegations that he was involved in the murder of a young drug dealer while in custody during one of his father's governments.[3] Figueres sued the authors of the book accusing him, and won, but the controversy was still used by Corrales in campaign, to no avail as Figueres won the primary election. Corrales did not support him afterward.[3]
The negative campaign continue after the primaries. Rodríguez used the "Chemise Case" too and also accused Figueres of not being Catholic and belonging to the Christian Science cult, of having a military upraising due to his father's past as revolutionary caudillo and the fact that he's a West Point graduate, etc., in order to caused fear of an authoritarian government.[3] Figueres campaign on the other hand tried to show Rodríguez as a cold, heartless entrepreneur with neoliberal ideas as a counterpart to Figueres socialdemocratic ideology.[3]
