The Iowa Caucus baffles many Americans. It’s the first "vote" of a presidential campaign. But its processes are a little mysterious.
There’s some kind of poll by both parties for each of the 99 counties and 1681 precincts in the Hawkeye state. Some precincts pool their efforts, so that, in all, there are about 900 separate community Caucus meetings.
And that’s one of the most unusual things: That people actually have to go out in the evening on Caucus day and listen to an hour or two of speeches before making their choice.
