Assembly of First Nations (National Indian Brotherhood before 1982) leadership elections are held every three years to elect the national chief of the Assembly of First Nations. Each chief of a First Nation in Canada is eligible to cast a vote. Currently there are 633 eligible voters. AFN rules state that a candidate needs 60% of the votes to win the election. If multiple candidates are on the ballot, the candidate with the fewest votes on each ballot is dropped until one candidate has reached the required percentage of votes. Additionally, any candidate who receives less than 15 per cent of the vote on a ballot is automatically dropped. If only two candidates remain, however, the candidate with fewer votes is not dropped from the ballot automatically, but rather the race continues to another ballot until the leading candidate reaches 60 per cent or the trailing candidate voluntarily concedes.
