County conventions must be held during a twelve-month period ending March thirty-first of every general election year during a month determined by the state committee as provided in Section 7-9-100. The county committee shall set the date, time, and location during the month designated by the state committee for the county convention to be held; however, the date set by the county committee for the county convention must be at least two weeks prior to the state convention. When a month in a nongeneral election year is chosen for the county convention, it must be held for the purpose of reorganization only. The date, time, and location that the county convention must be reconvened during the general election year to nominate candidates for public office to be filled in the general election must be set by county committee. Notices, both for the convention to be held for reorganization and for the reconvened convention to nominate candidates, must be published by the county committee, once a week for two consecutive weeks, not more than three nor less than two weeks, before the day in a newspaper having general circulation in the county. The convention must be composed of delegates elected from the clubs in the county, one delegate for every twenty-five members and major fraction thereof, based upon the number of votes polled in the first primary of the preceding general election year or based upon the number of votes for presidential electors at the last preceding general election therefor from the precinct as determined by the state committee. The same basis must be used in all precincts; or if the last preceding nominations were by convention, the representation must be based upon the number of votes for presidential electors at the last preceding general election therefor from the precinct. The list of delegates certified to by the president and secretary of each club shall constitute the temporary roll of the county convention. Where new precincts have been created or where the areas of precincts have been redefined, the party executive committee of the affected counties shall apportion delegates from the clubs representing the precincts.
