"Yes-No" voting is a type of voting system in which voters respond with a vote of "yea" or "nay" to a single alternative, such as a bill or an amendment, that is pitted against the status quo. A "yes" vote means that the voter is in favor of the issue at hand, while a "no" vote means that the voter is against it. The rules that specify exactly which collections of "yea" votes yield passage of the issue at hand are known as a yes-no voting system.

Examples of yes-no votes include voting on a contract ratification, a strike, bylaw amendments, or an unopposed candidate. In some cases, a yes-no vote can be used to choose a governing coalition in a parliament after the seating of its members.

The meaning of a "yes" or "no" vote can vary depending on the specific issue being voted on. For example, in Ohio, a "yes" vote on Issue One would raise the threshold to change the state constitution from at least 50% to at least 60%, making it harder to enact any kind of meaningful change. On the other hand, a "yes" vote on Colorados Proposition HH would allow the city to keep excess marijuana tax revenue and use it for affordable housing and homeless services.

In summary, a "yes" vote means that the voter is in favor of the issue at hand, while a "no" vote means that the voter is against it. The specific meaning of a "yes" or "no" vote can vary depending on the issue being voted on.
