The Iowa caucuses were precinct caucuses to select attendees to the county convention which will select attendess to the State convention in June which will then select delegates to the National Convention. Thus the Precinct caucus is only the beginning of selecting the delegates and those selected at the precinct level aren’t necessarily bound by the results as it depends upon how each precinct sets up their rules.
