The 2020 members of the society of game theorists are holding the annual election for their leadership board. All members are initially on the board, and are ranked based on their qualifications. They start off by voting on whether to keep the board the same size; if they fail to get a strict majority, the member with the lowest rank is expelled. This process continues until they finally vote to keep the size of the board intact.

At the end of this process, how many society members will remain on the leadership board?
