In NY state, we found an old guy, who just happened to be the head of the local Democratic Committee, behind one of the old lever voting machines when they opened the polls at 6:00 am on election day. The Democrats just happened to win, with more votes on that machine then any other. Yet “ no problem with the machine or voting were found.”
The NC Constitution states that the election shall be held on “one day”. Go figure.
Those old lever machines have paper tape that one could literally write votes onto, then slide the window shut then open the curtain lever which recorded the votes and stored the written tape votes for later counting. That was one way one could use to defeat the majic tumblers or weightings put into the lever machines
