Tony Gonzales is running against Brandon Herrera (R, challenger - rematch); Francisco Canseco (R, former congressman); Keith Barton (R); Susan Storey Rubio (R, rancher).
TX-23 is a proxy war between centrist and hard-right factions of the Republican Party. Gonzales was censured by the Texas GOP in 2023 for voting for the Bipartisan Safer Communities Act (the only Texas Republican to do so, representing Uvalde) and the Respect for Marriage Act. His 2024 primary opponent Brandon Herrera, a gun-rights YouTuber known as "The AK Guy," lost by just 354 votes in the runoff (50.6%-49.4%) and is back for a rematch. Despite party tensions, Trump endorsed Gonzales for 2026 -- his first endorsement of Gonzales after staying neutral in prior cycles. As Chairman of the Congressional Hispanic Conference, Gonzales is the most prominent Latino Republican in the House.
The general election is rated Solid/Safe Republican by Cook, Inside Elections, and Sabato's Crystal Ball -- the real fight is in the March 3 primary. Gonzales leads fundraising with $1.77M raised and $2.48M cash on hand vs. Herrera's $864K raised and $721K COH. Former Rep. Francisco Canseco, who held this seat in 2011-2013, is also running. TX-23 is the largest border district in the country (800+ miles, larger than 30 states, spans two time zones). Gonzales won the 2024 general 62.3%-37.7% over Democrat Santos Limon.
Key dates to watch: Primary on March 3, 2026 and General Election on November 3, 2026.
