Turning in for the night. So far, it looks like almost one suicide bomber per hour in Baghdad, though the low death toll seems to imply that the bombers are not completely penetrating security. Voter turnout is heavy in the Kurdish north and Shia south, and in sections of Baghdad. Turnout "extraordinary" in Basra. Turnout is light in Sunni areas. The violence is surprisingly light, hopefully the rest of the day will go as well.
