Laura Chinchilla
Chinchilla was one of two vice-presidents elected under the second Arias administration (2006–2010). She resigned the vice-presidency in 2008 in order to prepare her run for the presidency in 2010. On 7 June 2009 she won the Partido Liberación Nacional (PLN) primary with a 15% margin over her nearest rival, and was thus endorsed as the party's presidential candidate.
