Steve Carbo, director of the Democracy Program, said voters should be allowed to cast provisional votes even if they vote in the wrong precinct, a practice many states now forbid.
Florida Republicans in Jacksonville have been busy compiling and disseminating lists that many believe will be used to challenge minority voters today.
(A report, "Securing the Vote, a Report on Election Fraud," would suggest the Republicans' concerns are overstated. The paper, released by the nonprofit group Demos, shows that election fraud is at most a minor problem across the 50 states and does not affect election outcomes.)
