Texas's 22nd congressional district of the United States House of Representatives covers a largely suburban southwestern portion of the metropolitan area. The district includes most of Fort Bend County, including most of the cities of Sugar Land, Rosenberg, Needville and the county seat of Richmond as well as the county's share of the largely unincorporated Greater Katy area west of Houston. In addition, the district also contains portions of northern Brazoria County, including most of Pearland and Alvin and all of Wharton and Matagorda counties, as well as a small portion of western Harris County centered on most of that county's share of the Greater Katy area.

The district is represented by Republican Troy Nehls, who was elected in 2020 over two-time challenger Democrat Sri Preston Kulkarni. From 2009-2021 Texas's 22nd Congressional District was represented by Pete Olson. From 1985 until 2006 the district was represented by former House Majority Leader Tom DeLay and before that, former Congressman and three-time presidential candidate Ron Paul briefly in 1976 and again from 1979 to 1985.

The Cook Partisan Voting Index, which derives its data from the two most recent presidential elections, gave the district a R+10 lean compared to the national average until its 2021 review, when it was lowered to R+4 before redistricting. The district is currently rated R+9.

History The district was originally created in 1958, replacing the abolished at-large district represented by Democrat Martin Dies, Jr. from 1953 to 1959. At the time, all of Texas's 254 counties had representation by one collective member of Congress. The new district was placed in Harris County, home to the city of Houston and previously represented in its entirely by Democrat Albert Thomas in the state's 8th congressional district, making Harris the first county in Texas since World War II to be divided into more than one congressional district.

The new 22nd district, largely made up of suburban territory outside of Houston along with southern portions of the city itself, was won by Democrat Robert R. Casey, a former Harris County Judge (a post equivalent to that of a county executive in Texas). The 8th and 22nd districts were separated by a boundary consisting roughly of what is now U.S. 290, the western and southern portions of Loop 610, and the portion of Buffalo Bayou east of downtown Houston including the Houston Ship Channel. All points south of this boundary were in the 22nd, while the remainder was in the 8th. These boundaries would remain effective until the 1964 elections.

After a federal court in Houston ruled Texas' congressional redistricting practices as unconstitutional in Bush v. Martin, effective with the 1966 elections, Harris County was split between three congressional districts. In addition to the existing 8th and 22nd districts, a new 7th district was created on the west side of Houston and Harris County. The new 7th would elect former Harris County Republican Party chairman (and future President) George H. W. Bush, while Casey's 22nd district was made the most compact of the three, stretching from southwest Houston to southeast Harris County, including Pasadena and Clear Lake City, and also encompassing the Johnson Space Center.

1970 redistricting Following the 1970 census, the 22nd lost some largely African-American portions to the newly realigned, majority African-American 18th district (which would elect Democrat Barbara Jordan), while other areas along the Houston Ship Channel went to the 8th district, now represented by Democrat Bob Eckhardt and primarily concentrated in north Houston.

Those areas were replaced by portions of rapidly growing Fort Bend and Brazoria counties, home to growing Republican constituencies of white upper-middle-class families — natives and transplants alike — moving to jobs in Houston's growing energy sector, as well as at the Johnson Space Center and the Texas Medical Center, and drawn to affordable housing and top-rated schools in the area's burgeoning master-planned communities. A mid-decade redistricting in 1974 added southern Waller County, with a similar character to Fort Bend and Brazoria. As with most growing exurban areas in the Southern United States, these new areas also had large blocs of conservative white Democrats disenchanted with their party's support for restoration of civil rights promoted by the administration of Lyndon B. Johnson and the national Democratic Party. While Casey continued to win reelection in 1972 and 1974 without significant opposition, his resignation following his appointment to the Federal Maritime Commission in 1976, combined with increased suburban growth in the aforementioned counties, opened the door for a Republican upset in the special election that followed.

Three months after Casey's resignation, on April 3, 1976, Republican Ron Paul, a physician and Air Force veteran who had moved from the Pittsburgh area in the previous decade with his wife and settled in Brazoria County, won a special election to fill the remainder of Casey's unexpired term. Paul had been Casey's Republican opponent in 1974. While Paul lost the general election later that year to Democratic State Senator Bob Gammage by fewer than 300 votes, in 1978 he defeated Gammage in a general election rematch by a 1,200-vote margin, coinciding with the election of Bill Clements as Texas's first Republican Governor since Reconstruction. In 1980, Paul would go on to win a second term, defeating Democratic attorney Mike Andrews, a former Harris County prosecutor, by a narrow margin.

1980 redistricting Following the 1980 census, rapid growth in the Houston area resulted in most of the more Democratic areas of the 22nd being transferred to the new 25th congressional district, which Mike Andrews won in 1982 and would hold for six terms before pursuing an unsuccessful run for the Democratic nomination for U.S. Senate in 1994.

The redistricting left Paul with a district comprising three major portions, all of which were strongly Republican. These included:

all of Fort Bend County, by this time a booming suburban county anchored by the development of the First Colony master-planned community in Sugar Land, and also containing other booming suburbs including Missouri City, Stafford and Rosenberg. much of Paul's political base in Brazoria County, except for a tiny western portion around the communities of Sweeny and West Columbia located in the adjacent 14th district; and most of southwest Houston and Harris County along the Southwest Freeway, including the Westwood, Sharpstown and Fondren areas of Houston. This portion also included the Richmond Avenue entertainment corridor, The Galleria and the adjacent Transco Tower, the inner suburbs of Bellaire and West University Place, Houston Baptist University, and Greenway Plaza including The Summit (then the home of the NBA's Houston Rockets). Much of the area's retail activity, centered on the aforementioned Galleria as well as the Sharpstown and Westwood malls, along with most of southwest Houston's automotive dealerships (some of them among the top dealers in the nation), was also concentrated in the Harris County portion of the district and extended as far south as Stafford (then home to a major manufacturing facility for Texas Instruments).

This configuration would remain in effect for the remainder of the 1980s, including the first four terms of Republican Tom DeLay's tenure, as Paul unsuccessfully sought the Republican nomination for the United States Senate in 1984 against eventual winner Phil Gramm. DeLay served as chairman of the conservative Republican Study Committee and became a Republican whip while representing this configuration of the district.

1990 redistricting After the 1990 census, the 22nd remained largely unchanged. It covered all of Fort Bend County, all of Brazoria County save for its western and southern edges, and a small portion of southwest Houston around the Alief, Westchase and Sharpstown areas. The district was further reconfigured after the 2000 census, taking effect after the 2002 elections, when DeLay was re-elected and became House Majority Leader. The district lost Fort Bend County's share of Houston, but picked up a large slice of southeast Harris County, including portions of Clear Lake City, Pasadena, La Porte, Deer Park and Seabrook.

2000 and 2003 redistricting In 2003, following the Republican takeover of the Texas House of Representatives, the Texas Legislature engineered a mid-decade redistricting. The 22nd lost its share of Brazoria County except for Pearland, as well as communities on Fort Bend County's northern and western edges, to the 14th district. That district was now represented by Paul, who was elected and returned to Congress in 1997 after a 12-year absence. The 22nd district now included Pearland, almost all of southeast Harris County, including the Johnson Space Center, and a largely working-class western portion of Galveston County, including Santa Fe and La Marque, in addition to much of DeLay's political base in Sugar Land, Missouri City, Rosenberg and surrounding areas. The district would remain unchanged through the rest of the decade, but changed its incumbent three times after Tom DeLay resigned on June 9, 2006 in the wake of corruption allegations related to the 2003 redistricting.

As the result of a special election on November 7, 2006 to fill DeLay's vacant congressional seat, Republican Shelley Sekula-Gibbs filled the remainder of DeLay's term in late 2006, having lost the general election to Democrat Nick Lampson in a bizarre set of circumstances. Lampson had previously represented Texas's 9th congressional district, based in Beaumont and Galveston, before the 2003 redistricting resulted in that district being renumbered as the 2nd district and pushed into heavily Republican northern Houston. Lampson was defeated in the 2004 election by Republican Harris County district court judge Ted Poe. Ahead of the 2006 election, Lampson moved to Stafford, where his grandparents had settled after they immigrated from Italy. Additionally, the 22nd included a large slice of his former base; he'd previously represented much of the Galveston County portion of the district, as well as the area around the Johnson Space Center. Lampson benefited from Sekula-Gibbs being forced to run a write-in campaign, as DeLay had resigned one month after winning a contentious Republican primary against three challengers (one of whom won over 20 percent of the vote, but not enough to overcome DeLay's vote of over 60 percent). After just one term and despite a vigorous campaign, Lampson lost the seat to Republican Pete Olson in 2008. The district reverted to form, with Olson winning the district in 2010 by a double-digit margin.
