Ok, and of the students who had President votes how many were males?
SELECT DISTINCT count ( * )  FROM STUDENT AS T1 JOIN VOTING_RECORD AS T2 ON T1.StuID   =   T2.President_VOTE WHERE T1.sex   =  "M"
students who had President votes refers to joining STUDENT table with VOTING_RECORD table on StuID = President_VOTE; count males refers to WHERE sex = 'M'; distinct count of students refers to COUNT(DISTINCT <column>) which is not explicitly required but implied by the distinct keyword in the query;
