Iowa Code § 43.95: Calling convention to order.

When the delegates, or a majority thereof, or when delegates representing a majority of the precincts, thus elected, shall have assembled in the county convention, the convention shall be called to order by the chairperson of the county central committee, who shall present the certified list of delegates and members of the county central committee. If the convention is being held after the primary election, the chairperson shall also present a list of the offices for which no nomination was made at the primary election by reason of the failure of any candidate for any such office to receive the legally required number of votes cast by such party therefor.
