If the amendment passes statewide, but is rejected in Jefferson County, this article shall not be effective until a favorable vote is given by the voters of the county thereon. The governing body of Jefferson County may call and provide for holding a referendum for the purpose of determining if this article shall become operative. The election shall be held and the officers appointed to hold same in the manner provided by law for holding other county elections in the county and the returns thereof tabulated and results certified as provided by law for such elections.

The costs of the election, including the cost of notice by publication, shall be paid out of the general funds of the county. On the ballot to be used for such election, the question shall be in the following form:

"Do you favor the operation of bingo games by qualified organizations for charitable purposes in Jefferson County?" If a majority of the votes cast in the referendum are yes, bingo games shall be legal within Jefferson County, and this article shall become operative therein: if the majority of the votes cast in the election are no, this article shall have no further effect until if, in a subsequent referendum, a majority of the votes cast are yes, provided that two years have elapsed between the dates of such elections.
