 PSB was criticized in the press for how the poll was carried out because the company used members of a Venezuelan group called Súmate for fieldwork.The group had been involved in organizing the recall and were considered anti-Chávez by the Venezuelan government.In a paper published in academic journal Latin American Perspectives, Daniel Hellinger stated that the results of the poll "were very likely skewed by overrepresentation of voters in areas where [Súmate] volunteers were willing to conduct their interviews."
