Votes are counted differently in Iowa, since it is a caucus, not a primary.
Before everyone "votes", each caucus site will have someone supporting each candidate to speak. And they will enumerate the reasons to choose their candidate.
Then you either raise your hand or gather in a group for a headcount for each candidate to tabulate the totals. The results are phoned into state Headquarters. The results make it into the DM paper the next day, by location.
What appeared in the paper in 2012 was exactly the count from my caucus site.
After that takes place, the people running it ask you to stay & discuss the state party platform. That's when at least half the attendees leave, including myself.
Have heard that Democrats will argue for hours over minutiae, Republicans might last a while too. But have never stuck around for that.
Which is why the results pile up in random order.
Hopefully that explains a little bit how it transpires here.
