Answer

The Convener will introduce or seek a temporary Caucus Secretary. Ideally, each convener will have selected a Caucus Secretary in advance, but if not, your are highly encouraged to help them out.  It can be a real challenge to BOTH run the Caucus and record key information that must be submitted to the BPOU, including who has been elected to delegate/alternate and Precinct Officer positions. 

It is generally expected (and encouraged) for the temporary Caucus Secretary to be elected to serve as the permanent Caucus Secretary.
