I'd not be too surprised if you're right there. In a voting system where results get announced before all the votes are even in,let alone counted, nothing would surprise me.

I've always thought the availability of a write-in option was one feature of American voting that could usefully be adopted generally.

Someone said that in Australia there's a none-of-the-above write-in option, and if it got a majority they'd have to have a fresh election. Now that is something really worth having. I'm sure it would send the number of people who go to vote way up through the ceiling.
