Happened in Florida in 2012. I saw it with my own eyes at Orange County Supervisor of Elections Office in Orlando.  It was Monday, 11-05-2012.  Early Voting was closed.  The General Election was to start at 7 am on Tuesday, 11-06-2012.  You'd think there would be no voting on that day. But there was!  I saw it my own eyes-- buses in the parking lot across the street.  People lined up around the corner of the supervisor of Elections office and people were voting.  They were actually feeding ballots into tabulating machines. I reported it to FDLE.  No knowledge that anything happened to prosecute.
