Miss. Code § 23-15-295
When any person has qualified in the manner provided by law as a candidate for party nomination in any primary election, such person shall have the right to withdraw his or her name as a candidate by giving notice of his or her withdrawal in writing to the secretary of the proper executive committee at any time before the printing of the official ballots, and in the event of such withdrawal the name of the candidate shall not be printed on the ballot. When a candidate for party nomination for a state or district office who has qualified with the state executive committee withdraws as a candidate as is herein set forth after the sample of the official ballot has been approved and certified by the state executive committee the secretary or chair of the State Executive Committee shall forthwith notify the county executive committee of each county affected or involved of the fact of the withdrawal and such notification shall authorize the county executive committees to omit the name of the withdrawn candidate from the ballot if such notification is received before the printing of the ballot. In the case of the withdrawal of any candidate, the fee paid by the candidate shall be retained by the state or county executive committee, as the case may be.
