This squares with my experience in Illinois after a couple of elections.<p>* As a security/integrity issue, the ballots themselves are much less scary than the pollbooks, which are what we use to match voters against the voting rolls.<p>* Everything's ultimately on paper; there are bar codes, which nobody loves, but they're auditable against the readable printed ballot.<p>* Most of the security is physical/human; for us, each polling station (a location can have several precincts and thus several stations, each a giant rolling metal box) is sealed using numbered plastic seals before the polls open and after they're closed, and everything is recorded redundantly and signed off on by the poll workers.<p>* A matching count at the close of polls is a <i>big deal</i>, a nightmare big deal; in Illinois, we can't just shrug off a missing ballot and say "nothing we can do about it"; in March, I had to stay 3 hours late while we resolved a similar issue (IIRC, a mis-recorded provisional). Most pollworkers in my experience are there for the money (I've never bothered cashing the check) and the threat that they won't get paid if they count doesn't match is extremely powerful.<p>* The local police are not allowed to monitor polling places, and the municipality of the polling place is usually confused about that; in Cook County, it's the County Sheriff's Department that has authority over polling places. Our cops were very friendly and responsive.<p>* The drama of every election is the the "string line" that defined the 100 foot "no electioneering" radius of the polling place; the entertainment you can count on each cycle is the candidate whose people religiously move their lawn signs inside the string line, and freak out when you remove them.<p>It's an interesting system that derives a lot of resiliency from extreme complexity and maximal human touch points --- Illinois elections will never do something with 1 person when the same thing could be done with 2 --- which is sort of the opposite of how we reason about security online. It's simultaneously terrifying and reassuring.
