When I entered the electronic voting machine booth to vote, selections had already been made in all the voting categories. The previous voter's choices were still showing, including his write-in vote. I notified the poll worker who said "how did he escape?" and he entered the booth. He pushed the "Cast Vote" button twice, but nothing seemed to happen. He exited and pushed some buttons on the control panel, which cleared the votes. I then entered my votes which appeared to be cast correctly. Afterwards, the poll worker the machine had problems earlier in the day, too, possibly related to having a write-in vote, but he wasn't sure. He did not know if the vote before mine was cast two or three times, or at all. No matter what I saw all the selections of the previous voter.
