First ballot: 2/3 of the entire membership 630 members, 420 votes needed to win Final (fourth) ballot: a majority of members present 620 members present, 311 votes needed to win
The election takes place by secret ballot. A two-thirds supermajority of the whole membership is needed to win on the first ballot. On the second and third ballot, a two-thirds supermajority of votes cast (including blank ballots among the totals) suffices. Starting from the fourth ballot, the threshold is further lowered to a simple majority of members present.
