Bush counties. A suit by the National Association for the Advancement of Colored People (NAACP v. Harris) argued that Florida was in violation of the Voting Rights Act of 1965 and the United States Constitution's Equal Protection Amendment. A settlement agreement was reached in this suit with ChoicePoint, the owner of DBT Online, a contractor involved in preparing Florida's voter roll purge list. Four counties distributed sample ballots to voters that differed from the actual ballot used on election day, including Duval County, which used a caterpillar ballot, so called because the list of presidential candidates stretched over two pages. The instructions on the sample ballots said "Vote every page". More than 20% of ballots in black precincts of Duval County were rejected because of votes for president on each page. Further, counties and precincts with large black populations disproportionately had technologies where ballots would predictably go uncounted. In punchcard counties, 1 in 25 ballots had uncountable presidential votes. In comparison, counties that used paper ballots scanned by computers at voting places (in order to give voters a chance to correct their ballot if it had an error) had just 1 in 200 uncountable ballots. A systematic investigation by the United States Commission on Civil Rights concluded that although blacks made up 11% of Florida's voting population, they cast 54% of the uncounted ballots. Between May 1999 and Election Day 2000, two Florida secretaries of state, Sandra Mortham and Katherine Harris, contracted with DBT Online Inc., at a cost of $4.294 million, to have the "scrub lists" reworked. In a May 2000 list, over 57,000 voters were identified as felons, with all counties being ordered to remove all listed names from their voting rolls. Democrats claimed that many simply had names similar to actual felons, some listed "felonies" were dated years in the future, and some were random. Some counties refused to use the list, finding it error-ridden. In other counties, supervisors of elections notified those at risk of being scrubbed, giving them a chance to prove they were not felons, which a small number chose to do. In most cases, those on the scrub list were not told that they weren't allowed to vote until they were turned away at the polls. An estimated 15% of the names on the county lists were in error. Florida was the only state in the nation to contract the first stage of
