Voted in Vegas yesterday. Noted the following “quirk” in touch screen choices: if you didn’t touch exactly in the circle next to your choice, your choice went to another one, either above or below. No one tells you how important it is to touch exactly in the box or circle of your choice. To game the system, it is possible to create the touch screen in such a way as to benefit some other result than your choice. Checking the accuracy of the touch screen in the circle or box will not detect the game. If then you slip your choice beyond the limits of the outline, the scam works. Just a thought.
