Kleberg County is represented in theTexas House of Representatives byJosé Manuel Lozano, aRepublican party politician.[18]Kleberg County has leaned Democratic most of its history but has become more competitive in the 21st century. An indicator of that trend is Lozano, who was originally a Democrat but switched to the Republican party in 2012. Kleberg County Attorney Kira Talip Sanchez was originally elected as a Democrat in 2014 but switched parties in August 2023 and is now a Republican.[19] No candidate from either party has managed to reach 60% of the vote share in a presidential election since Jimmy Carter in 1976.
Compared to the rest of the ancestral Democratic stronghold of South Texas, Kleberg County has seen a relatively mild swing towards the Democrats - for example, in 2024, the county voted to the left of nearbyStarr County for the first time in its history. Some of this may be attributed to Kleberg County's lower Hispanic population, especially in rural areas.
