Tom Sell holds a commanding lead in the Texas 19th Congressional District Republican primary runoff scheduled for May 26 due to his 40 percent showing in the March 3 primary, superior fundraising exceeding $1.2 million, and endorsements from multiple former primary opponents along with agricultural and business groups. His background in West Texas law practice, prior congressional staff work, and focus on local farming and rural policy priorities have consolidated support in this heavily Republican district. Abraham Enriquez trails after advancing with roughly 19 percent, emphasizing national alignment issues. Traders assign minimal probability to an upset, though lower-than-expected turnout or late shifts in voter mobilization could narrow the margin before resolution.
