Prior to the 2000 census (when Wisconsin lost a seat in Congress), the 5th District was a Milwaukee district, with vastly different boundaries and political history, represented often by Democrats or even Socialists. The district now numbered the 5th was primarily encompassed in Wisconsin's 9th congressional district until the abolition of the latter.
