I agree that voting forms should really only be in English. You have to learn it to become a naturalized citizen and I would hope that any natural born citizens already know it. To play devil's advocate, I guess that some natural born citizens of immigrant parents could be home schooled, thus never being forced to learn English. I think this is a very small demographic however. To apply general productivity/efficiency logic to this, I don't know that it's worth the effort to cover a <1% case. It's not like you even have to read much to register to vote. Get somebody at the voter registration place to help you if you can't understand enough English to fill out basic demographic fields.
