I voted in Nevada last week. I believe the screen sensitivity is an issue. I noticed in the news story this morning that the peole were using their fingers in the Clark County (Vegas) story. Here in Washoe County (Reno) they give you a pencil with an eraser at each end to use on the machine. The screen change has been sped up since the last election and the machine responds very fast. I would submit that there is a programming issue if it comes up with Reid's AFTER the voter selects “English” which is on the first screen, Reid name is under the select English box.
BTW the machine will print a paper copy of your ballot before you record the vote so verification can be accomplished.
