In 2008, there were more than 4,000 precinct caucus sites.

Or, on Feb. 7, they can go to one of 576 caucus sites and vote the old-fashioned way.

Participants indicate their support for a particular candidate by standing in a designated area of the caucus site (forming a preference group).

A 15 percent threshold was required in order to receive delegates at any caucus site.

In addition, those who turn 18 by the general election are eligible to register at the caucus site.

When they sit down, a packet of Forbes information identifying their caucus site is already at their seat.

All you had to do was show up at a caucus site and fill out a voter registration card.

The results are based on 1,660 voters in 50 randomly selected caucus sites, interviewed as they were entering each site.

At hundreds of caucus sites the final preparations are being made and in less than an hour the doors will be closed.

In a state with 4,000 precincts, there were only 42 caucus sites.
