O.C.G.A.    21-2-501   (2010)
   21-2-501.    Number of votes required for election 
      (a)  Except  as otherwise provided in this Code section, no candidate shall be  nominated for public office in any primary or special primary or elected  to public office in any election or special election unless such  candidate shall have received a majority of the votes cast to fill such  nomination or public office. In instances where no candidate receives a  majority of the votes cast, a run-off primary, special primary runoff,  run-off election, or special election runoff between the candidates  receiving the two highest numbers of votes shall be held. Unless such  date is postponed by a court order, such run-off primary or special  primary runoff shall be held on the twenty-first day after the day of  holding the preceding primary or special primary, provided that, unless  postponed by court order, a runoff in the case of an election or special  election shall be held on the twenty-eighth day after the day of  holding the preceding election or special election; provided, however,  that, in the event that a special election is held at the time of a  general primary, any special election runoff shall be held at the time  of the general primary runoff. If any candidate eligible to be in a  runoff withdraws, dies, or is found to be ineligible, the remaining  candidates receiving the two highest numbers of votes shall be the  candidates in the runoff. The candidate receiving the highest number of  the votes cast in such run-off primary, special primary runoff, run-off  election, or special election runoff to fill the nomination or public  office sought shall be declared the winner. The name of a write-in  candidate eligible for election in a runoff shall be printed on the  election or special election run-off ballot in the independent column.  The run-off primary, special primary runoff, run-off election, or  special election runoff shall be a continuation of the primary, special  primary, election, or special election for the particular office  concerned. Only the electors who were duly registered to vote and not  subsequently deemed disqualified to vote in the primary, special  primary, election, or special election for candidates for that  particular office shall be entitled to vote therein, and only those  votes cast for the persons designated as candidates in such run-off  primary, special primary runoff, run-off election, or special election  runoff shall be counted in the tabulation and canvass of the votes cast.  No elector shall vote in a run-off primary or special primary runoff in  violation of Code Section 21-2-224.
(b)  For  the purposes of this subsection, the word "plurality" shall mean the  receiving by one candidate alone of the highest number of votes cast. If  the municipal charter or ordinances of a municipality as now existing  or as amended subsequent to September 1, 1968, provide that a candidate  may be nominated or elected by a plurality of the votes cast to fill  such nomination or public office, such provision shall prevail.  Otherwise, no municipal candidate shall be nominated for public office  in any primary or elected to public office in any election unless such  candidate shall have received a majority of the votes cast to fill such  nomination or public office.
(c)  In  instances in which no municipal candidate receives a majority of the  votes cast and the municipal charter or ordinances do not provide for  nomination or election by a plurality vote, a run-off primary or  election shall be held between the candidates receiving the two highest  numbers of votes. Such runoff shall be held on the twenty-eighth day  after the day of holding the first primary or election, unless such  run-off date is postponed by court order. Only the electors entitled to  vote in the first primary or election shall be entitled to vote in any  run-off primary or election resulting therefrom; provided, however, that  no elector shall vote in a run-off primary in violation of Code Section  21-2-216. The run-off primary or election shall be a continuation of  the first primary or election, and only those votes cast for the  candidates receiving the two highest numbers of votes in the first  primary or election shall be counted. No write-in votes may be cast in  such a primary, run-off primary, or run-off election. If any candidate  eligible to be in a runoff withdraws, dies, or is found to be  ineligible, the remaining candidates receiving the two highest numbers  of votes shall be the candidates in such runoff. The municipal candidate  receiving the highest number of the votes cast in such run-off primary  or run-off election to fill the nomination or public office sought shall  be declared the winner. The municipality shall give written notice to  the Secretary of State of such runoff as soon as such municipality  certifies the preceding primary, special primary, election, or special  election.
(d)  The name of a municipal  write-in candidate eligible for election in a municipal runoff shall be  printed on the municipal run-off election ballot in the independent  column.
(e)  In all cities having a  population in excess of 100,000 according to the United States decennial  census of 1980 or any future such census, in order for a municipal  candidate to be nominated for public office in any primary or elected to  public office in any municipal election, he or she must receive a  majority of the votes cast.
(f)  Except for  presidential electors, to be elected to public office in a general  election, a candidate must receive a majority of the votes cast in an  election to fill such public office. To be elected to the office of  presidential electors, no slate of candidates shall be required to  receive a majority of the votes cast, but that slate of candidates shall  be elected to such office which receives the highest number of votes  cast.
