“I’d like to make things as convenient as possible,” Orr said. “That is probably stretching it a bit too far. I am not sure if that is really necessary. Going to Monday, remember for security reasons and so forth, we have to collect all of these cartridges, all this equipment, and that is all taking place when people need to be going to bed early.”

“It is an extraordinary task,” Orr said. “In all the years I have been running the elections I have never seen anything like this. This is extraordinarily challenging. Our people are hanging in there. Working very long hours and hoping no one get sick. We like the idea of providing a lot of opportunities for voters, even though it makes our work very tough.”
