Straw poll
（重定向自Straw vote）
A straw poll or straw vote is an ad-hoc or unofficial vote.
Straw polls provide dialogue among movements within large groups. Impromptu straw polls often are taken to see if there is enough support for an idea to devote more meeting time to it, and (when not a secret ballot) for the attendees to see who is on which side of a question. However, in meetings subject to Robert's Rules of Order, straw polls are not allowed.
