We always have runoff elections. I'd be surprised the time we don't have one. Our party system is too fractured to have outright majorities unless the candidate is wildly popular.

Exit polls point to a runoff between Fujimori and Kuczynski. Fujimori has almost 40% and Kuczynski and Mendoza have around 20%-21%. With a less than 1% difference, it's still unclear who'll face Fujimori. Some say the Peruvians Abroad vote will give PPK the edge over Mendoza.
