The database is given to parties so they can audit if people live where they are voting, or even if they live for that matter. Not giving them access is not an option, if you want the continue having a voting system that does not require trust, as the mexican voting system was designed to allow.<p>I agree that the database should be made public for all citizens, as it currently stands, only parties registered for elections get a copy, and no doubt use it for their campaigns. This puts people outside of the party system in a disadvantage against the parties, particularly relevant for things like citizen initiatives.
