Is third time the charm for Keiko Fujimori in Peru? I'd imagine she could successfully beat Kuczynski in a rematch since his approval is in the low 30s. It's far off but is there a possibility she could run? What are your thoughts?
In 2021 the left will not be in government (= unpopular) and the leftist candidate will do a lot better. Verónika Mendoza will have national name recognition and be 40 rather than 35 (which many considered too young). That will make it harder for a Fujimorist too make the run-off.
PPK can not run for reelection and has no obvious successor, so his ratings don't matter much (and they are actually quite good for a Peruvian president).
