I would say that with the high schools, at the end of the election, that's a big part of it. Everybody sits down at the table and fills out their voter registration card, so I do believe that it's a huge influence with the high schools.
For the younger kids, they know when January comes around that they're going to get to vote. The reason I know this from both sides of the fence is that my sons both attended a school where they allowed the voting machines to come in, and they were really excited and proud about it and they talked about it in the weeks leading up.
I believe they do get a large number of registrations as a result of this program.
