(a) Regardless of whether state funds are requested for paying primary expenses, each county chair and state chair shall prepare a report that includes:

(1) an itemized list of the actual expenses incurred in connection with the general and runoff primaries by the authority preparing the report and by the executive committee over which the authority presides;
