The political party may elect to have delegates to the county convention register with the election commissioner or county clerk.
(2) If a political party elects to have delegates to the county convention register with the election commissioner or county clerk, such delegates shall register with the election commissioner or county clerk on or before March 1 of each year in which the political party conducts a county convention. The election commissioner or county clerk shall deliver to the state chairperson of a political party the roll, properly certified, showing the name, address, and precinct of each delegate registered for such convention, no later than March 15 of each presidential election year. If there is not a full quota of delegates for the county convention as established by the political party, the delegates at the county convention may select delegates to fill the quota from the registered voters affiliated with the political party in the county.
