In the first round of voting in April, several centrist candidates divided their support, leaving two extremists carrying worrisome relationships: Ollanta Humala, a populist, nationalist who sometimes sounds like a more extreme version of Venezuela's Hugo Chavéz, and Keiko Fujimori, daughter of Peruvian ex-President Alberto Fujimori, who turned himself into a dictator and made corruption and human rights violations state policy and is now in a Peruvian prison.
This is a surprising situation for Peru. The country's economy has grown at 9 percent annualy - the fastest rate in South America - so you'd expect voters to choose another centrist who'll continue the existing economic and political policies. But too many centrist candidates divided that vote between them. The situation is also a testament to the fact that despite Peru's economic boom, many Peruvians live in poverty.
Perhaps the election winner will learn from others' mistakes. Recently, Humala has tried to distance himself from Hugo Chavez and Keiko Fujimori, who is leading in the polls, has tried to the same from her father's administration.
