In 2001, the National Opinion Research Center (NORC) at the University of Chicago, sponsored by a consortium of major United States news organizations, conducted the Florida Ballot Project, a comprehensive review of 175,010 ballots that vote-counting machines had rejected from the entire state, not just the disputed counties that were recounted. The project's goal was to determine the reliability and accuracy of the systems used in the voting process, including how different systems correlated with voter mistakes. The study was conducted over a period of 10 months. Based on the review, the media group concluded that if the disputes over the validity of all the ballots in question had been consistently resolved and any uniform standard applied, the electoral result would have been reversed and Gore would have won by 60 to 171 votes. On the other hand, under scenarios involving review of limited sets of ballots uncounted by machines, Bush would have kept his lead. In one such scenario — Al Gore's request for recounts in four predominantly Democratic counties — Bush would have won by 225 votes. In another scenario (if the remaining 64 Florida counties had carried out the hand recount of disputed ballots ordered by the Florida Supreme Court on December 8, applying the various standards that county election officials said they would have used), Bush would have emerged the victor by 493 votes.
