Kan det också betyda valmanskår, jag tycker inte valkrets passar i det sammanhang
På wikipedia:
A constituency is any cohesive body of people bound by shared identity, goals, or loyalty.
Constituency can be used to describe a business's customer base and shareholders, or a charity's donors or those it serves.
In politics, a constituency can mean either the people from whom an individual or organization hopes to attract support, or geographical area that a particular elected official represents.
