Oh goodie, so Latin America is slipping back into their self made letist cesspool of old.
Sea Parrot --> the Peruvian elections have multiple candidates and 2 rounds -- if in the first round no one wins 50%+ of the vote, then the top two candidates face off in the second round.
This time what happened was that the two right-wing candidates: Luis Losso and Keiko Fujimori were leading. But then there came two politicians with a centrist policy: Pedro Kyczynski and Alejandro Toledo.
People didn't trust humala or fujimori, but the central votes were split
Hence the run-off was between the leftist and Fujimori.
The Peruvians had two bad choices -- and they picked one. They did not "swing" so much as shrug with no options and trudge.
