The Laredo city government is a strong city council – weak mayor system. The mayor presides over the eight-member city council, but he/she may only vote to break a tie. City Council elections are based on single-member districts and campaigns have no party affiliations. Municipal elections are now held in November (formerly in May) of even-numbered years. The municipal government is administered by the city manager hired by the city council. All city elected offices have a four-year term and are nonpartisan though most officials have a Democratic party preference or affiliation. One member of the city's 8-member Council is associated with the Texas Green Party
