The 'Help America Vote Act' provides federal money for voting precincts to institute optical scan balloting systems. These are 'fill in the bubble' type ballots which will help prevent voters from making mistakes by spitting the ballots out of the machines in certain circumstances.
Eaton County currently provides optical scan ballots in some precincts, but other still carry punch cards, lever machines, or even simple paper ballots. Eaton County Clerk and Register, Fran Fuller says it's a question of money and priorities that many precincts haven't already updated to optical scan.
However, not updating causes some problems with the training of voter workers, with four different ballot processes; they need to have four different training methods.
While Eaton County is not exclusively using optical scan ballots, they have been in use in the county for about ten years.
