President Donald Trump (R), U.S. Sens. Lindsey Graham (R-S.C.) and Josh Hawley (R-Mo.), and former Texas Gov. Rick Perry (R) endorsed Jackson. Incumbent Rep. Mac Thornberry (R), who did not seek re-election, endorsed Winegarner, along with U.S. Reps. Mike Conaway (R-Texas), Lance Gooden (R-Texas), and Kenny Marchant (R-Texas).
Thornberry, who was first elected in 1994, won his last election in 2018 by a margin of victory of 65 percentage points. Major independent observers rate the general election as solid Republican or safe Republican.
