I've read several articles on how a caucus works, but my question is, in a couple of the articles I read they indicated the members met in homes.
Is each meeting a particular precinct? If that was the case, in my area, they'd have to have pretty large meeting halls in order for people to attend a caucus.
The meeting location is based on what they expect to need for room. In some rural precincts it could be a house, but school auditoriums or halls are probably more common.
And the bit about if one candidate doesn't receive 15%, then they basically disqualify that candidate and revote, that seems so weird to me. With a large field of candidates isn't there a remote possibility (not in this race, but perhaps in another race) that each candidate would receive under 15%. For instance, what if all 9 ran in Iowa, and each had a constituency that was under 15%, then what would they do????
They go until they get a winner that meets the cut. It is an opportunity to make cases for the various candidates and try to sway people to the candidate of your choice.
WHile it may seem arcane it is a very informative process, though stamina can help more than position on issues.
In the end this is where county delegates are selected (to represent a specific candidate, and they goes on to select state delegates for the national convention.
It isn't a short process, and not as instant gratification as poll results, but it is open and pushes dialog.
