Are your proof readers retarded monkeys?

New York county prints ‘Barack Osama’ on ballots

Barack 'Osama' on Rensselaer County ballots

I'm not a statistician (but if you are and can crunch the numbers on this please get back to me), but I find it hard to believe that something like this making it by 3 rounds of proof readers is just a coincidence. I mean seriously... either someone's trying to be sneaky or they have Ray Charles, Hellen Keller and Stevie Wonder as their proof-reading team.

My reasons:
1. It's one of the presidential candidates, which I'm sure they usually pay extra attention to.
2. Any time people see the word "Osama" in post-9/11-Bush-They-Hate-Our-Freedom-World people practically soil their drawers.
