In Florida, the counties are supposed to drop felons off the voting roles.
The use a list provided to them by a company called "Database Technologies"
 (I think) (out of Texas).   After the election Database Technologies
admitted that the list they provided to Florida did not include all the
felons that should have been on the list AND worse yet... the exclusion
list included about 8000 voters that only had misdemeanors NOT felonies.
When challenged they said it wasn't their fault... the list of criminals
that was incorrect came from.... the state of Texas.

Glitch tells hundreds in Florida they are felons who can't vote

By Marcia Gelbart
Palm Beach Post Staff Writer

TALLAHASSEE -- With less than five months left before November's
presidential election, hundreds of Palm Beach County and Treasure Coast
residents came within a few erroneous keystrokes this week of losing their
voting rights. A computer error by a Boca Raton company that has a $4
million contract with
the state Division of Elections mistakenly singled out thousands of
Floridians -- including 472 in Palm Beach County and 185 from the Treasure
Coast -- as felons in Texas and a few other states. No Floridian convicted
of a felony can vote unless his voting rights are restored by the Office of
Executive Clemency.

Initially, 11,986 people were tagged with out-of-state felony convictions.
But after the mishap was realized, following angry complaints from people
erroneously identified as muggers, burglars and car thieves, 7,972 people
were removed from that list."   .... there is more, you'll just have to go
to the Palm Beach Post newspaper website and read it.

Also from Newsweek September 29, 2000

"A. GLENN BRASWELL, a Florida-based mail-order magnate who once served
seven months in federal prison for perjury and mail fraud, has contributed
$220,000 to Republican causes during the past two years—including $25,000
to George W. Bush’s gubernatorial re-election campaign in 1998 and another
$125,000 in “soft money” donations to the Florida Republican Party, federal
and state records show. "

Note -- After the story broke the Bush campaign gave the money back.
