In presidential election years the ballot provided for in section 16.1-06-05 must include the designation of the office of president and vice president as the first listing of the continuous listing of the designation of each office to be voted for. The names of presidential electors, presented in one certificate of nomination, must be arranged in a group enclosed in brackets under the designation of the office of president and vice president on the right side of the ballot column. To the left and opposite the center of each group of electors’ names must be printed in bold type the surname of the presidential candidate represented and in line with such surname must be placed a single oval. A mark within such oval by the voter must be designated as a vote for all the electors. The appropriate party designation must appear, in smaller type, under the surname of the presidential candidate represented.
