The county has become more competitive since the 2010s, and has voted to the left of Texas as a whole.
Beginning in 2016, theDemocratic Party rebounded to represent a larger portion of the political profile and made huge gains in Tarrant County, concentrated in several areas throughout the county: eastern Euless, Grand Prairie and eastern and southern Arlington, northern and western areas of Mansfield, large portions of Fort Worth, particularly the area surrounding the Stockyards and Meacham Airport, southern and eastern Fort Worth, especially in dense metro areas and along I-35W, and Forest Hill.[37]
Republicans are dominant in many of the rural areas of the county, downtown and western Fort Worth and north of Loop 820, and almost all suburban areas including Benbrook, rural Mansfield areas and western Arlington, Haltom City, Mid-Cities (Hurst, Euless, and Bedford), and the northern suburbs.[37] Tarrant County has consistently voted Republican in gubernatorial elections since1994.[38]

Many other suburban Texas counties, including Tarrant's immediate neighborsDenton andCollin, as well as those aroundHouston andAustin, showed similar trends between 2016 and 2020.[40] However, in the2024 election Tarrant County moved back in the Republican column, supporting Trump overKamala Harris, 51.8% to 46.7%.
