At the presidential level, Lubbock County votes predominantly Republican, having voted Democratic for president only once in the past 70 years, a trend which began with native son Dwight D. Eisenhower heading the ticket in 1952 and 1956, reversing a trend typical of the Solid South. In the 2020 Presidential election, Joe Biden's percentage (a best for a Democrat since 1976), was due to Biden winning precincts within the city highway loop in Lubbock.[11] The heavy Republican lean of the county is mostly due to Republican landslide victories in precincts located outside the city highway loop in the county.
In October 2023 Lubbock County Commissioners passed a controversial "Sanctuary County for the Unborn" ordinance. The ordinance outlaws "the act of transporting another person along their roads for an abortion."[12]
