It was vandalism, but none of you realize why Gary Busey and why specifically 77 votes -- I recall that when Jon Stewart was reporting on the Ames caucus, he joked that even Gary Busey beat Jon Huntsman, and fake statistics popped up claiming Busey defeated Huntsman 77-69. I'll find the video in a few minutes, I need a laugh anyways.
EDIT: Here's the video. You can scroll forward to 3:28 to see the relevant sound-bite, though the entire video, where Stewart defends Paul and dismisses Santorum as a non-factor (and is very funny in general) is well worth a watch.
