Jon Bonck holds a dominant position in the Texas 38th Congressional District Republican primary runoff due to his first-round performance on March 3, where he captured nearly 48 percent of the vote against a crowded field, far ahead of Shelly deZevallos. His early endorsements from President Donald Trump and Senator Ted Cruz, combined with superior fundraising as a mortgage professional and local conservative activist, have consolidated support among Republican primary voters in the Houston-area district. The May 26 runoff remains the decisive contest, with traders assigning high implied probability to Bonck based on these structural advantages. Late shifts in turnout among key conservative blocs or unforeseen campaign developments could still alter the result before voting concludes.
