You may remember this reply to a post claiming 953 dead people voted in S. Carolina’s GOP primary.
Luckily, the Executive Director of the S. Carolina Election Commission testified on this issue.
According to her testimony, 37,000 people in the state have been identified as deceased. Of those 37,000, only 953 ballots have been cast in the names of those deceased. Based on this finding, they checked the list of 37,000 presumed deceased to see if any of them requested absentee ballots for the 2012 primary. They found 10 who had requested absentee ballots; all 10 are alive and well.
This kind of thing happens: deceased voters are not removed from the rolls, voters are presumed to be dead when they are - in fact - alive, etc.
