Rather than Voter ID, just point a video camera, like a security camera or red light camera, at the doorways of the voting booths. Then the video is EVIDENCE should there be people who vote multiple times. One problem is the cheaters don't get caught and hardly ever get punished. But, there is little expectations that much of that is unfolding.
I do love the expression from Rand that says part of the mission is to "just show up." That's part one of my theme song for a winning forumula: Show up. Part two is, Score more points.
