Here’s my bright-line — informed by years of “unintended acceleration” and tech support horror stories: Those who assert touch-screen errors must meet one of the following tests 1) Own and use a cell phone 2) Use an ATM at least twice a week 3) Only write paper checks for Girl Scout cookies.

Sorry, but the simplest explanation for perceived errors is that voters are leaning or bracing themselves on the screens, triggering boxes in the process. The possibility that machines “default” to straight ticket Democrat is crazed on its face — but for that reason cannot be completely ruled out. Because the vote machine business is a closed loop and not subject to normal technological checks, balances, and competition, there is no telling what kind of half-assed unintentional coding errors lurk in those black boxes.
