 Fort Bend County is often considered a swing county, with election results usually tilting more Democratic than statewide results, which almost always favor Republicans nowadays.Elections within the county are often decided by margins in more Republican-leaning areas in Sugar Land, Rosenberg, and southern Missouri City, with Republicans dominating in the Katy, Fulshear, and rural southern areas of the county and Democrats in the county's northeast corner around northern Missouri City and Fresno, as well as heavily Hispanic Mission Bend.Since the passage of the Voting Rights Act of 1965, the federal government has enforced it by regularly reviewing voting patterns and local practices, and plaintiffs have sometimes sued state or local governments over discriminatory practices.
