Voting Booths?

Heard on the radio, as the local drive-time guy was trying to address the differences between what we might espouse out loud and what we might actually do when it comes time to vote:

I'm thinking that if I could get into the ballot box, I might try to change those votes that couldn't be changed ahead of time by affecting hearts and minds.

Of course, I'm not sure how this will work with electronic voting.
