Marquette County was reliably Republican following the American Civil War; its voters went Republican (or Republican-splinter) in every election from 1876 through 1932. However, that shifted in 1936; since then the Republican nominee has carried the county in only 5 out of 21 elections (through 2016).
The county government operates Sawyer International Airport, the jail, maintains rural roads, operates the major local courts, records deeds, mortgages, and vital records, administers public health regulations, and participates with the state in the provision of social services. The county board of commissioners controls the budget and has limited authority to make laws or ordinances. In Michigan, most local government functions—police and fire, building and zoning, tax assessment, street maintenance, etc.—are the responsibility of individual cities and townships.
