U.S. Rep. Lamar Smith (R-San Antonio) will not seek re-election. In an email to supporters, Smith said it was time to “pass on the privilege of representing the 21st District to someone else.”

Smith was first elected in 1986.

House rules will prevent him from continuing as chair of the Science, Space and Technology Committee after 2018. Losing his chairmanship is also a reason why U.S. Rep. Jeb Hensarling (R-Dallas) opted not to seek re-election.

CD21 includes part of northeastern Bexar Co., all but far eastern strip of Comal Co., the central part of Hays Co., and all of Bandera, Blanco, Gillespie, Kendall and Kerr Cos. It substantially overlaps SD25, which is represented by Sen. Donna Campbell (R-New Braunfels). Campbell’s campaign website was dark after Smith’s decision became public, which could just be a coincidence. A spokesperson for Campbell said she is considering what is best for her and the district, tweeted the Texas Tribune’s Patrick Svitek.

Campbell received 45% of the vote in her 2010 race for what was then CD25 against U.S. Rep. Lloyd Doggett (D-Austin). CD21’s current configuration is much friendlier to a Republican candidate that the CD25 of 2010. However, Campbell would need to give up her seat to run for CD21, unlike her colleague, Sen. Bryan Hughes (R-Mineola), who is considering a run for open CD5. Campbell is up for re-election in 2018. Hughes’s seat is not up until 2020.
