After a week of early voting, a handful of glitches with electronic voting machines have drawn the ire of voters, reassurances from elections supervisors -- and a caution against the careless casting of ballots. Several South Florida voters say the choices they touched on the electronic screens were not the ones that appeared on the review screen -- the final voting step. In Broward County, for example, they don't know how widespread the machine problems are because there's no process for poll workers to quickly report minor issues and no central database of machine problems. Debra A. Reed voted with her boss on Wednesday at African-American Research Library and Cultural Center near Fort Lauderdale. Her vote went smoothly, but boss Gary Rudolf called her over to look at what was happening on his machine. He touched the screen for gubernatorial candidate Jim Davis, a Democrat, but the review screen repeatedly registered the Republican, Charlie Crist. A poll worker then helped Rudolf, but it took three tries to get it right, Reed said. Broward Supervisor of Elections spokeswoman Mary Cooney said it's not uncommon for screens on heavily used machines to slip out of sync, making votes register incorrectly.
