I did something very similar to this for my high school's prom queen vote who I wanted to win for teenager reasons. The voting system was just a bunch of laptops in front of the lunch room running a web app and all that was needed to vote was to know a student id. A few hours and some javascript later, I voted more than the entire senior class. It was only discovered after the event.
