Peru’s compulsory voting system, combined with a registered electorate of over 27 million, has historically produced first-round turnout near or above 70 percent in recent presidential contests. Pre-election assessments pointed to sustained participation despite widespread voter fatigue from repeated political turnover and concerns over insecurity, though logistical delays on April 12–13 and elevated rates of null or blank ballots introduced modest downward pressure. The resulting consensus range of 70–75 percent reflects these baseline dynamics and the limited scope for major deviations once counting neared completion. Shifts into adjacent brackets would require either substantially higher abstention tied to unresolved disputes or unexpectedly robust mobilization in rural and overseas districts, neither of which materialized in final tallies.
