The newspaper was criticized for publishing a daily poll which gave President Enrique Peña Nieto an 18-point lead over Andrés Manuel López Obrador 5 days before the election, while the real difference was 6.46%. Ciro Gómez Leyva printed a public apology, adding that they would "retire from electoral polling."[1]
