Miss. Code § 21-5-5
The mayor and councilmen (or commissioners) of all cities operated under the commission form of government shall be elected from the city at large, but the municipal authorities may establish as many wards and as many voting precincts in each ward as may be necessary or desirable. No person shall be eligible to the office of mayor or councilman unless he is a qualified elector of such city and shall have been a bona fide resident thereof for a period of at least one year next preceding the date of the commencement of his term of office.
In the event the council should ordain that the councilmen posts shall be separated, as provided in Section 21-5-11, such post shall be so separated for election purposes and persons seeking the office of councilman shall qualify and seek election for a specific post, as designated by ordinance, and each post shall be voted on separately by the qualified electors of the municipality voting in said election.
In the event there should be but one candidate for one of such election posts, or only one candidate for each of such posts, then such candidate or candidates shall be declared to be elected.
