Florida Voter File Contract
In 1998, the state of Florida signed a 4 million USD contract with Database Technologies (DBT Online), which later merged into ChoicePoint, for the purposes of providing a central voter file listing those barred from voting. As of 2002, Florida is the only state which hires a private firm for these purposes. Prior to contracting with Database Technologies, Florida contracted with a smaller operator for 5,700 USD per year. The state of Florida contracted with DBT in November 1998, following the controversial Miami mayoral race of 1997. The 1998 contracting process involved no bidding and was worth 2,317,800 USD.
ChoicePoint has been criticized, by many critics of the 2000 election, for having a bias in favor of the Republican Party, for knowingly using inaccurate data, and for racial discrimination. Allegations include listing voters as felons for alleged crimes said to have been committed several years in the future. In addition, people who had been convicted of a felony in a different state and had their rights restored by said state, were not allowed to vote despite the restoration of their rights. (One should note Schlenther v. Florida Department of State (June 1998) which ruled that Florida could not prevent a man convicted of a felony in Connecticut, where his civil rights had not been lost, from exercising his civil rights.) Furthermore, it is argued that people were listed as felons based on a coincidence of names, despite other data (such as date of birth) which showed that the criminal record did not apply to the voter in question.
Journalist Greg Palast has argued that the firm cooperated with Florida Governor Jeb Bush, Florida Secretary of State Katherine Harris, and Florida Elections Unit Chief Clay Roberts, in a conspiracy of voter fraud, involving the central voter file, during the US Presidential Election of 2000. The allegations charge that 57,700 people (15% of the list), primarily Democrats of African-American and Hispanic descent, were incorrectly listed as felons and thus barred from voting. Palast estimates that 80% of these people would have voted, and that 90% of those who would have voted, would have voted for Al Gore. The official (and disputed) margin of victory, in the election, was 537 votes.
ChoicePoint Vice President Martin Fagan has admitted that at least 8,000 names were incorrectly listed in this fashion when the company passed on a list given by the state of Texas, these 8,000 names were removed prior to the election. Fagan has described the error as a "minor glitch". ChoicePoint, as a matter of policy, does not verify the accuracy of its data and argues that it is the user's responsibility to verify accuracy.
On April 17, 2000, at a special Congressional hearing in Atlanta, ChoicePoint Vice-President James Lee testified that Florida had ordered DBT to add to the list voters who matched 80% of an ineligible voter's name; middle initials and suffixes were to be dropped, while nicknames and aliases were added. In addition, names were considered reversible, for example; Clarence Thomas could be added in place of Thomas Clarence. Lee opened his testimony by noting that ChoicePoint intended to get out of the voter purge industry. Then, on February 16, 2001, DBT Senior Vice-President George Bruder testified before the US Civil Rights Commission that the company had misinformed the Florida Supervisors of Elections regarding the usage of race in compiling the list. Greg Palast concludes, "An African-American felon named John Doe might wipe out the registration of an innocent African-American Will Whiting, but not the rights of an innocent Caucasian Will Whiting." Palast believes that 80% of the 57,700 people allegedly barred from voting were African-American.
