Cook Political Report’s PVI map and district list is the primary source for the Cook Partisan Voting Index. The page is the official list used to show each district’s PVI ratings.

Ballotpedia’s district page states that, heading into the 2024 elections, the Cook Partisan Voter Index for Texas’s 23rd Congressional District was R+5. This is the clearest directly quoted PVI value available in the provided results, but it does not show R+7 for 2026.

Ballotpedia’s article on the Cook Political Report’s Partisan Voter Index includes a Texas district table that lists Texas’s 23rd District as R+1 in the shown dataset, indicating a district-specific PVI value different from R+7.

The infobox for Texas's 23rd congressional district lists its Cook Partisan Voting Index (CPVI) as "R+7". It presents this as the current PVI associated with the district as configured beginning with the 2026 election. The page describes the 23rd as a majority Hispanic district stretching across southwestern Texas and notes changes beginning with the 2026 election.

Cook Political Report’s TX-23 2026 race page exists for the district and identifies it as a 2026 House race page. The provided search result snippet does not expose any PVI rating, so it does not confirm the claim of R+7.

The Cook Political Report homepage describes the publication as an independent, non-partisan newsletter analyzing elections and campaigns for the U.S. House, Senate, governors, and president. This supports it as the authoritative source to check for a district’s PVI, but the snippet provided does not state TX-23’s rating.

The page for the 2026 election in Texas' 23rd Congressional District lists basic election information such as primary and general election dates. However, it does not state an updated Cook Partisan Voting Index value for TX-23 heading into the 2026 elections, and instead links back to general district information where the PVI is given as R+5 for the 2024 cycle based on 2016 and 2020 presidential results.

The overview page for the 2026 United States House of Representatives elections in Texas lists the upcoming contests for all 38 districts. For Texas's 23rd congressional district, it describes the seat as vacant following the resignation of Representative Tony Gonzales in 2026 and notes that the district stretches across the southwestern portion of the state. The article references the district’s Cook PVI indirectly via a link to the district’s main page, which shows a value of R+7.

A Facebook group post dated January 20, 2026 links to The Cook Political Report and discusses updated Cook ratings. The post quotes from Cook’s materials and highlights changes in certain districts’ ratings ahead of the 2026 elections. Although TX-23’s PVI is not visible in the snippet, the post indicates that Cook issued updated information in early 2026 relevant to House races.

Third Way’s report "How to Build a House [Majority]" explains that "Cook’s PVI scores use results from the last two presidential elections to measure the partisan nature of each Congressional district." It further notes that the set of "Majority Maker" districts consists of those with PVI scores within the D+5 to R+5 range. The report uses Texas’s 23rd Congressional District as an example of a competitive seat and describes its demographic and electoral characteristics, illustrating how analysts rely on Cook PVI metrics when assessing districts like TX‑23.

The "Find a Race" tool on Cook Political Report allows users to search and filter House races across the country by state, race type, and CPR Race Rating. It is the entry point for viewing specific district information such as ratings and potentially Cook PVI values. However, detailed data for individual districts, including TX-23 for 2026, is behind a login wall and not accessible from the public page.

The New York Times interactive "Texas 23rd Congressional District 2026: Latest Polls" presents polling data for the 2026 general election in TX-23. It notes that Republicans are entering the 2026 midterms with a 217-212 majority in the House, with five seats currently vacant, and situates TX-23 within that broader context. The page focuses on polling rather than the Cook Partisan Voting Index, but it reflects contemporary analysis of TX-23’s competitiveness ahead of the 2026 vote.

The official "Find Your Representative" tool on House.gov, when queried with ZIP code 78872, reports: "Zip code: 78872 is located in the 23rd Congressional district of Texas. The representative for this district is: Tony Gonzales -- Vacancy Republican." This confirms the existence and current vacancy status of Texas’s 23rd district and its association with Republican representation, which aligns with its Republican‑leaning PVI classification in election analyses.

In discussing Nevada’s 2nd Congressional District, the Club for Growth PAC notes that it is "a Republican-leaning seat with a PVI of R+7" and elsewhere describes another competitive House race as having "a Cook PVI of R+5". These references show how partisan voting index values like R+7 and R+5 are used to characterize districts’ partisan lean, but the page does not mention Texas’s 23rd congressional district or provide a PVI figure for TX-23.

The Federal Election Commission’s page for the 2026 U.S. House election in Texas’s 23rd District provides campaign finance data for candidates and committees. It includes information on receipts, disbursements, and spending trends, but it does not address the Cook Partisan Voting Index or any other measure of partisan lean for the district.

The Facebook post from FOX7 Austin discusses the race for the Republican nomination in Texas’ 23rd congressional district and notes the Texas GOP’s efforts to support Republican candidates down the ballot. It comments on the competitiveness of the district but does not mention a specific Cook Partisan Voting Index value such as R+7 for TX-23.

The Texan’s Texas Partisan Index is a different measure from Cook PVI. Its table shows TX-23 at R-55% / R-54% in the cited rows, but this is not Cook’s Partisan Voting Index and should not be treated as evidence for the claim.

Wikipedia’s Cook Partisan Voting Index page includes a table listing Texas 23 as R+7. This is a tertiary source and the table is not presented as a primary measurement release, but it is consistent with the specific claimed value.

According to standard usage by the Cook Political Report, a district described as "R+7" in PVI terms is one whose average Republican presidential performance over the last two presidential cycles is seven percentage points stronger than the national result. This general definition of PVI is widely cited in election analysis and is used to interpret claims like "Texas’s 23rd congressional district has a Cook PVI of R+7 heading into the 2026 elections."

270toWin’s 2026 House ratings page is a secondary election-forecasting resource. The provided snippet does not show a Cook PVI for TX-23 and therefore does not directly support the claim.
