Other forms: bread-and-butter issues
A bread-and-butter issue is one that affects everyday people, like tax rates or road conditions.
Basic, fundamental matters are bread-and-butter issues. Issues that have some connection to money are often described this way too, especially by politicians and journalists. Historically, the term bread-and-butter has been used in various ways, especially in the United States and Canada, to mean either something basic — like enough income to live on — or ordinary.
