With the Texas House Democrats likely returning to Austin this week for a new legislative special session, the Republican redistricting map appears set to become law.
The new plan is drawn in response to the US Justice Department informing the state leadership that a recent en banc 5th Circuit Court of Appeals decision pertaining to minority district composition made certain Texas congressional districts illegal.
For political reasons, Republicans are making the most of the redrawing opportunity to craft more favorable districts for their incumbents and candidates. With the Hispanic vote particularly in South Texas turning more GOP favorable, a new map has the potential of producing significant Republican gains.
A byproduct of the redraw is the pairing of several Democratic US House members in newly constructed districts. The one attracting the most attention occurs in Travis County, where Austin-based House members Lloyd Doggett and Greg Casar are preparing for a head-on battle to represent the new 37th CD, which is fully contained within the county and will be heavily Democratic.
Earlier this week, Rep. Doggett released an open letter to his key supporters informing them of his intention to run in new District 37 and suggesting Rep. Casar run in the new 35th District. The 35th contains none of Travis County and is anchored in San Antonio, but a district in which Casar currently sees an approximate 10 percent overlay between the population of his current CD and that part of the new TX-35.
Part of the new CD 35 configuration is similar to Rep. Casar’s current Austin-anchored district, but the addition of Republican voting counties east of San Antonio help create a significantly Hispanic seat that President Trump carried by approximately 10 percentage points.
Casar, who is currently the chairman of the House Progressive Caucus and served for seven years on the Austin City Council, quickly rejected Rep. Doggett’s suggestion. Therefore, we can expect both men to compete for new District 37.
The new 37th, however, is comprised mostly of Rep. Doggett’s territory from his current 37th CD. In the new configuration, 68 percent of the new TX-37’s populace is currently in Rep. Doggett’s domain versus just 32 percent who reside in Rep. Casar’s current district, according to The Down Ballot political blog researchers.
The Federal Election Commission 2nd Quarter disclosure reports also reveal another major Doggett edge. For the ’26 election cycle, Rep. Doggett has raised only a little over $130,000 but sits on a war chest of more than $6.2 million. Rep. Casar posted in excess of $264,000 raised for the current year and holds slightly over $450,000 in his campaign account, less than 10 percent of the money that Rep. Doggett commands.
The looming Doggett-Casar contest is another example of some Democratic primaries popping up around the country that pit an older incumbent against a young rising star. In this case, Rep. Doggett is 78 years old and will be 80 by the time of the next election. He has been a House member since 1995.
Prior to winning a congressional seat, Doggett served as a Justice of the Texas Supreme Court after initially winning election to the state Senate in a 1973 special election. He also ran unsuccessfully for the US Senate in 1984, losing to Republican Phil Gramm.
Casar, 36, was elected to the House in 2022 after taking his seat on the Austin City Council in 2014. An advantage he may have in the new 37th is the large Travis County Hispanic population. The new district configuration yields a Hispanic base of close to 38 percent, but the proportion will certainly be higher among likely Democratic primary voters. The remainder of the populace is comprised of approximately 44 percent Anglo residents, 10 percent who are Black, and eight percent Asian.
The Texas map also pairs Democratic members in two other districts. It is likely that Rep. Marc Veasey (D-Ft. Worth) would lose his Tarrant County power base and run in a new 33rd CD that is fully contained within Dallas County. It is possible that freshman Rep. Julie Johnson (D-Farmers Branch/Dallas), who faces only poor options for re-election, could run against Rep. Veasey.
In Houston, the winner of the November (and possibly early January election should the first vote lead to a runoff, which is likely) special election will have to immediately turn around and face veteran Rep. Al Green (D-Houston) in a new 18th CD that will contain a large portion of the Congressman’s current 9th District.
Once the map becomes law, incumbents and candidates will then make definitive decisions regarding the districts in which they will run.
