As I said once before...
...I think electronic is the way to go. But only when security is absolute, the entire process is transparent, and you can call each and every vote back to how (and if) it was counted. Until we achieve this, we will have big and small problems. If the shit hits the fan in a close presidential election, then there will be screaming about it for another 8 or 10 years. We have the technology to fix this mess. We don't have a good excuse not to.
