Miss. Code § 23-15-683
In any elections, as soon as the deadline for the qualification of candidates has passed, or forty-five (45) days prior to the election, whichever is later, absentee ballots shall be prepared and printed for the elections, and both of said ballots shall have printed thereon the names of all candidates who originally qualify as candidates. However, such ballots shall be printed on paper of different tints or colors and shall be styled so as to show which ballot is to be used for the first election and which ballot is to be used for the second election.
When the proper application is made as is otherwise provided herein, the registrar shall send to the absent voter the proper absent voter ballots for the elections as is otherwise provided herein, and with such ballots there shall be sent also separate official envelopes for the return thereof. No additional ballot shall be thereafter sent to the absent voter for the second election but the absent voter shall ascertain which of the candidates who originally qualified are candidates in the second election and he or she may vote for his choice between them on the second election ballot previously sent him. If an absentee voter shall vote for any candidate on the second election ballot who is not a candidate in the second election, his vote for that office shall be disregarded.
