In my case the people in the county board of elections

left off ONE letter from my absentee ballot and when I never got it they said oops they misentered the address
and left off one letter from the mailing address so it was returned..

also I can imagine human error from the elections people leaving out a number from the mailining address or writing the wrong one down causing the same problem..

I hope someone realizes there is a lot of room for human error between the board of elections and post office that people should know about...
