Well, I certainly don't see anything wrong with exploring other options for proving where you live. That would help only those students who live on campus, and of course, I am talking more generally about students who can live anywhere. But I think that rather than looking at things that we can add or change at this point, we do have a fairly good system in place in vouching that I have used myself and that my friends have used and other students have used. I think it works quite well to do exactly what you've stated.
Students right now can get proof from housing if they wish to vote, but many students who use vouching are often the ones who live off campus and are faced with many of the problems that I outlined in my remarks.
