re: Hearing about voters not being able to vote.... Paper ballots

I just tried to vote, have voted many times and it has been at the same place for the last 6 years. This time however they said my name was not on the list. Not just for that particular polling place but not listed in the county I live in. I had to go to a completely different location and do an affidavit to vote.(How many people would have just left and said "to hell with it"?) Side note, both places I had to go to and from what everyone here at work says it has all been paper ballots. (Mississippi)
