While the media chases race-driven narratives, Texans are focused on something bigger. I bleed Texas red. I’m a proud father and husband, a veteran who served this nation, a West Point graduate, an America First patriot, and a follower of Christ. This campaign isn’t about division—it’s about preservation. When we win this Texas Senate race, we will secure our conservative future and defend the values that make Texas the strongest, freest state in America. #Texas #senate #txsenate #wesleyhunt
