Polls According to a poll of Mexico City residents by the newspaper Reforma, 65% of those polled believed that there was fraud and that there should be a full recount. A poll of Mexico City residents on August 9 by the newspaper El Universal found that 59% believed that fraud had occurred, and 63% believed there should be a full recount of all the votes.
