Similar problems have also been discovered yet again in Maryland (see here for a story by the Baltimore CBS affiliate).

With many electronic voting machines more than a decade old, and states lacking the funding to repair or replace them, officials have opted to return to the pencil-and-paper voting that the new technology was supposed to replace. . .
