Texas's 21st congressional district of the United States House of Representatives serves the area north of San Antonio and a significant portion of Austin in the state of Texas. Towns entirely or partially in this district include Boerne, Fredericksburg, Ingram, Kerrville, Kyle, New Braunfels, and San Marcos. The current Representative from the 21st district is Chip Roy.

The district was created in 1934, and has always been anchored in the Texas Hill Country and northern San Antonio. However, until the early 1980s, it stretched for some distance into West Texas, as far as Big Bend National Park. It began shifting away from its Yellow Dog Democrat roots in the late 1960s, though it took until 1978 for a Republican to win it. The GOP has held it ever since, in large part due to the increased growth of the San Antonio suburbs. The district was pushed into the Austin area in the 1980 census; until the 2000s it included fast-growing Round Rock.

Recent election results

2006 In the case of League of United Latin American Citizens v. Perry, 548 U. S. 399 (2006), the U.S. Supreme Court ruled that the configuration of Texas' 15th, 21st, 23rd, 25th and 28th congressional districts as drawn by the Texas Legislature violated the National Voting Rights Act of 1965. Replacement district boundaries for the 2006 election were subsequently issued for the five districts by the local federal district court, and on election day in November, these five districts had open primaries, with candidates being elected for receiving over 50 percent of the vote. Runoff elections were held in December to decide elections in which no candidate gained an absolute majority in November.Austin American-Statesman accessed 4 August 2006; link broken 18 October 2006

In the 2006 election, Lamar Smith defeated veteran and college administrator John Courage with 60% of the vote.

2016

2018 Lamar Smith did not run for reelection in 2018.

On the Republican side, 18 candidates competed in the March 6 primary, in which no one received a majority. The first- and second-place finishers were, respectively, attorney Chip Roy, who served as chief of staff to Sen. Ted Cruz (R-Tex.) and senior advisor to Texas Gov. Rick Perry (R), and Matt McCall, owner of a business providing human tissue for American military hospitals. Roy and McCall advanced to a May 22 runoff, which Roy won with 52.7% of the vote.

On the Democratic side, four candidates ran to replace Smith: Joseph Kopser, entrepreneur and Army veteran; Derrick Crowe, activist; Elliott McFadden, executive director of Austin B-cycle; and Mary Street Wilson, pastor. No one received a majority in the March 6 primary, so the top two finishers, Wilson and Kopser, advanced to a runoff on May 22. Kopser flipped the primary result in the runoff against Wilson, winning the nomination with 58% of the vote.

2020 The incumbent, Chip Roy, was unopposed for the Republican nomination. Former state Senator Wendy Davis won the Democratic primary runoff. Tom Wakely was nominated by the Green Party caucus.
