The St. Petersburg Times offers this very interesting report. A snippet:

Nov. 5, 1996, marked a historic night. Osceola County elected its first Hispanic to a local office. It symbolized how Hispanics were reinventing this community in the shadow of Disney’s theme parks.
But on the same ballot, voters eliminated the system of single-member districts crucial to Guevara’s victory.
After Guevara, Osceola forced candidates to run countywide, where white voters still make up the majority.
And since then, no other Hispanic has won a local election in Osceola County, even though more and more are running. Hispanics account for one in three Osceola voters.
Now, in a rare move for the Bush administration, the U.S. Department of Justice is suing Osceola under the Voting Rights Act, claiming that countywide districts discriminate against Hispanics.
It’s one of the first times the Bush administration has used the Voting Rights Act, designed to help black voters, to ensure that Hispanics have the opportunity to elect their preferred candidates.
