About this election
The electoral system
The president is elected under Argentina's two-round rule — more than 45%, or more than 40% with a ten-point lead, to win outright, otherwise a run-off between the top two. The compulsory PASO primaries in August 2023 had stunned the political class by putting Milei in first place nationally, confirming that the contest was now a three-way race between the libertarians, Peronism and the traditional centre-right.
