Voter turnout in Peru's June 7 presidential runoff between conservative Keiko Fujimori and leftist Roberto Sánchez is expected to land in the 70-80% range, consistent with the first-round figure of roughly 74%. Mandatory voting with fines for abstention provides a structural floor, while the narrow gap between the two finalists and ongoing campaign mobilization could sustain participation near prior levels. Lingering effects from April's logistical delays, extended polling hours, and public distrust—evident in elevated blank and null ballots—may temper enthusiasm for some segments. Recent confirmation of the runoff candidates in mid-May has introduced limited new catalysts, leaving the outcome sensitive to any late shifts in turnout among key demographics or renewed confidence in electoral processes.
