  Title: Peruvian general election, 1990
  Passage: General elections were held in Peru on 8 April 1990, with a second round of the presidential elections on 10 June.  The run-off was between favorite, novelist Mario Vargas Llosa leading a coalition of economically liberal parties collectively known as the Democratic Front and political underdog Alberto Fujimori of the populist and more moderate Cambio 90.  Vargas Llosa won the first round with a fairly low number of the votes, but alienated much of the electorate with a comprehensive privatisation agenda, bolstering the allegedly unelectable Fujimori.  Fujimori eventually won a landslide victory and would remain president for ten years until he was ousted in 2000.
