The use of the controversial Diebold machines has received anything but a warm welcome since it was chosen as the main voting system in Memphis and Shelby County elections more than 4 years ago. With the reported irregularities now stemming from this month's primary and county races, yet another organization is ready to turn up the heat again on the Shelby County Election Commission to make a change.

"We believe that the smoking gun, as it relates to this election, are the machines themselves," said Greg Grant, President of the National Action Network's Memphis chapter.

At a Wednesday news conference held on the steps of the downtown election commission office, members of the local chapter of the National Action Network became the latest to independently jump into the fray just hours before the official certification of election results on Thursday.

"We found that hundreds, if not thousands, of people were turned away. We feel that those numbers can very easily affect the outcome of any number of elections that were held on that particular day," said Grant. "We've asked the Reverend Al Sharpton to come here and deal with the Federal Voting Rights Act of 1965. In that, deal with those individuals who were disenfranchised on Election Day, those individuals that were turned away."
