Peru's conservative Keiko Fujimori and leftist Roberto Sánchez closed their presidential campaigns in Lima on Thursday before large crowds, ahead of a Sunday runoff that polls indicate is too close to call. The latest Ipsos survey puts Sánchez, a former foreign trade minister and ally of imprisoned ex-president Pedro Castillo, at 43.8% against Fujimori's 43.2%, with 13% of voters undecided. The result carries regional significance, as a Fujimori victory would add to a recent wave of right-wing electoral wins across Latin America, while a Sánchez win would mark a revival of the left in a country that has cycled through eight presidents in a decade.
