Design Flaw, or Not

So, when e-voting machines in Florida malfunction, why do they always malfunction in one particular way?

Roberta Harvey, 57, of Clearwater, Fla., said she had tried at least a half dozen times to select Kerry-Edwards when she voted Tuesday at Northwood Presbyterian Church.

After 10 minutes trying to change her selection, the Pinellas County resident said she called a poll worker and got a wet-wipe napkin to clean the touch screen as well as a pencil so she could use its eraser-end instead of her finger. Harvey said it took about 10 attempts to select Kerry before and a summary screen confirmed her intended selection.

How many voters, conditioned by endless "Are you sure?" dialog boxes, failed to check their ballot summary?
