US House
California Rep. Darrell Issa (R-San Diego)
At the end of last week, Rep. Issa announced that he will seek re-election and will do so in CA-48 despite the district now having a Democratic tilt.
The US Supreme Court approved the new Texas map late last week and declared that the 2025 plan will be in place for the 2026 election. The decision also affects the new California map since the pending lawsuits in both cases involved racial gerrymandering claims, meaning the voter-approved new Golden State map will almost assuredly be in place for the 2026 elections.
The justices timed their ruling to allow candidate filing in Texas to conclude today. Several key political determinations dominoes will fall, the most significant of which revolves around Rep. Jasmine Crockett’s (D-Dallas) decision to file for the Senate or House.
In a related choice, Rep. Marc Veasey (D-Ft. Worth), who sees his 33rd District now located wholly within Dallas County thus eliminating his Tarrant County political base, says he will file in Crockett’s District 30 if she announces for the Senate. If Crockett decides to remain in the House, Veasey will either file for District 33 or enter the race for Tarrant County Judge (labeled County Executive in other places).
Freshman Rep. Julie Johnson’s (D-Farmers Branch) 32nd District is transformed into a Republican seat that stretches into East Texas. Her plan is to reportedly file in District 33.
While California’s candidate filing will remain open until March 6 (March 11 if the incumbent in a particular race does not file), individuals are making decisions about where to seek election; hence, Rep. Issa’s plan to run in new District 48.
Under the 2021 California Citizens Redistricting Commission map that the legislature and voters replaced this year, Rep. Issa’s San Diego County-anchored 48th District held a partisan lean (according to the Dave’s Redistricting App organization) of 58.3R – 39.8D. Under the new plan, that ratio moves to 50.6D – 48.7R, a net swing of 20.5 data points in the Democrats’ favor.
Though this makes re-election much more difficult for Rep. Issa, he still has a fighting chance of defeating a Democrat in the general election. Several California districts with more lopsided Democratic partisan leans have elected Republican Representatives. Therefore, this seat likely moves from a Safe Republican rating to Toss-Up.
In comments posted in an X tweet, Rep. Issa also made some suggestions about other members in his delegation, most specifically the proposed pairing between Reps. Ken Calvert (R-Corona) and Young Kim (R-La Habra). At this point, both have announced for new District 40 (DRA partisan lean: 57.0R – 42.3D), but Rep. Issa was suggesting that Rep. Kim instead run in new District 45 where she would challenge freshman Rep. Derek Tran (D-Orange County).
From a Republican Party standpoint, such a move would make sense. Ironically, the state’s two most vulnerable Democratic members, the pair who won the closest US House elections in 2024 — Reps. Adam Gray (D-Merced; winning by 187 votes) and Tran (winning by 653 votes) — actually see their Democratic partisan ratios surprisingly reduced under the new map.
In District 13, Rep. Gray views a partisan swing that moves a net 4.3 data points in the Republicans’ favor, making the partisan lean, according to the Dave’s Redistricting App statisticians, of 52.4D – 46.9R. In 2022, Republican John Duarte won the 13th District that featured a partisan lean of 54.0D – 44.2R.
In southern California’s 45th CD, former Rep. Michelle Steel (R), who earlier announced that she will not return to run again in 2026, carried the seat in 2022 with a DRA partisan lean of 52.2D – 45.9R. The new 45th posts a 51.7D – 47.5R partisan lean, again suggesting that a Republican general election finalist will be competitive.
With the Supreme Court making the political situations clearer in at least the two most populous states, final 2026 electoral decisions in California and Texas can now be made with all candidates confident of which map will be in place. We will carry further analysis of the Texas situation after candidate filing closes later today.
