We identify frequent inaccuracies in journalistic interpretations of the horse race (“who is ahead?”) and of change over time (“who is gaining?”) in poll reports during the Canadian election of 2008. We test two explanations. The “mistaken mindset” hypothesis holds that journalists exaggerate the horse race because they systematically miscalculate the margin of error. The “follow-the-pollster” hypothesis holds that journalists follow the horse-race interpretations that they find in pollsters' reports. We find strong support for the “follow-the-pollster” hypothesis in the data and in interviews with pollsters and journalists and conclude that pollsters' reports should be a key element to consider in any attempt to improve the level of accuracy in media reports of the horse race. Résumé. Les journalistes ont souvent commis des erreurs d'interprétation de la marge d'erreur dans les résultats de sondages pendant la campagne électorale canadienne de 2008. Cela les a conduits à surestimer l'avance du parti gagnant et le changement dans le score d'un parti entre deux sondages successifs. Comment expliquer ces erreurs fréquentes? Une première hypothèse affirme que cette surestimation provient du fait que les journalistes se trompent systématiquement dans le calcul de la marge d'erreur. Selon une deuxième hypothèse, les journalistes connaissent tellement mal la marge d'erreur qu'ils se fient à l'interprétation qu'en font les maisons de sondage. Les données empiriques et les réponses aux questions d'entretiens soutiennent la deuxième hypothèse. Nous en concluons que pour mieux porter fruits, les efforts pour améliorer l'interprétation de la marge d'erreur devraient cibler les maisons de sondage autant que les journalistes
