According to a story in the Sacramento Bee, election officials in Yolo County (CA) have discovered that the instructions for voters with vision disabilities in their voting machines are only in Vietnamese:
Yet two weeks ago, when officials began programming the machines, the directions for use by voters with vision disabilities came out in Vietnamese.
The timing of the discovery — about one month before the Nov. 7 elections — lessened the shock. But the county’s top elections official said the error shows just how sticky the move toward electronic voting can be.
The good news is that the vendor (Hart) sent a corrected program within 72 hours of learning about the problem.
