What does "cannot do alone" mean?

The signature idea

Every office on your ballot has two lists: what it can do, and what it can do by itself. Most civic education stops at the first list. We think the second list is the more important one, because that is the list that predicts whether a campaign promise can actually be kept.

The County Mayor example

Under T.C.A. § 5-6-101 and Article VII of the Tennessee Constitution, the county mayor is the chief executive officer of the county. It sounds like the top of the county. In practice:

• The county mayor cannot set your property tax rate. The county commission sets the rate.
• The county mayor cannot direct the sheriff. The sheriff is separately elected under Article VII, § 1 and answers to the voters, not to the mayor.
• The county mayor cannot run the schools. The school board hires the director and sets policy.
• The county mayor cannot pass an ordinance alone. The county commission passes ordinances.

The mayor proposes a budget, appoints department heads for departments under the mayor's office, and represents the county — but three of the four things people most often want from local government sit outside that office's unilateral power.

Why this matters for evaluating candidates

When a candidate for county mayor promises to lower your taxes, ask which office would actually vote on the tax rate. When a candidate for governor promises to change your local school policy, ask which body actually writes the rule. The point is not that these officeholders are powerless — many of them are the single most influential voice in the room. The point is that the room votes, and one voice does not carry the whole room.

Where we apply this rule

Every office page on this site carries a "cannot do alone" section, sourced to statute and constitution. See it in action on the County Mayor page and the Governor page. For the reverse view — starting with an everyday topic and listing which offices actually decide it — see Who Controls This?.
