You should start with the question of why do you need someone to be in an office in the first place. And if the position is indeed so valuable and necessary, why can't you just hire and pay this person, instead of voting for him and asking him to take money out of you and others by force?
I would happily hire the leader of my choice, it's just that I don't have enough to pay him or her. Other people have money I could use, but they want to hire different people than I do. How to resolve all these differences? Voting.
You might also be shocked to learn that boards of directors, when considering candidates for CEO, usually resolve their differences by voting.
