<x-flowed>Obviously it is a matter for the constitution or by-laws of the organization. Some organizations, such as the Libertarian Party, require that there always be an alternative of "None of the above", meaning that the assembly can leave a position unfilled if no one steps forward that the majority can support. It's a good rule and one I recommend to other organizations.
