“An elephant passed in front of us and we did not see it” is the headline of a piece in Clarin, Argentina’s largest newspaper, after Javier Milei took 30% of the vote at last week’s open primaries, beating mainstream candidates on the left and right and putting himself in the position to possibly win the presidency in the general election in October.
