Well, as others had said, I wouldn't choose the polling place that has all the media set up because that would seem to be a prime target. And secondly, it seems logical that the terrorists would make early attacks in order to intimidate people from even thinking of voting. I probably wouldn't rush out to be among the first to vote at 7am. I'd wait a few hours and see how things went.
Allegra says the Iraqis are not early risers so things will be slow initially!
