A series of judicial rulings and subsequent legislative actions have initiated a comprehensive redistricting process across several U.S. states, significantly altering the electoral landscape ahead of the 2026 midterm elections.

一系列的法院裁決及隨後的立法行動，在美國多個州啟動了全面的選區重新劃分程序，在 2026 年中期選舉前顯著改變了選舉格局。

The current volatility in congressional mapping is primarily predicated upon the Supreme Court's decision in Louisiana v. Callais, which restricted the application of Section 2 of the Voting Rights Act of 1965. By determining that race cannot be the primary determinant in drawing legislative districts, the Court has facilitated the dissolution of majority-minority districts. Consequently, Republican-led legislatures in Tennessee, Alabama, and Louisiana have moved to eliminate Democratic-held seats. In Louisiana, Governor Jeff Landry suspended House primaries to permit the adoption of a 5-1 Republican-leaning map. Similarly, Tennessee has effectively erased its sole Democratic district. While South Carolina's Senate initially resisted such measures, Governor Henry McMaster has indicated a potential executive intervention to pursue redistricting.

目前國會選區劃分的波動，主要基於最高法院在「路易斯安那州訴 Callais 案」中的裁決，該裁決限制了 1965 年《投票權法》第二條的適用範圍。法院判定種族不能成為劃分立法選區的主要決定因素，從而促使了「少數族裔佔多數」選區的解體。因此，由共和黨領導的田納西州、阿拉巴馬州和路易斯安那州的立法機關已採取行動，旨在消除民主黨把持的席位。在路易斯安那州，州長 Jeff Landry 暫停了眾議院初選，以允許採用一張 5-1 傾向共和黨的地圖。同樣地，田納西州也實際上抹除了其唯一的民主黨選區。雖然南卡羅來納州參議院最初抵制此類措施，但州長 Henry McMaster 已表示可能會採取行政干預以推進選區重新劃分。

Stakeholder positioning reveals a stark divergence in strategy. The Congressional Black Caucus (CBC) characterizes these developments as a systemic regression of civil rights, with Chair Yvette Clarke estimating that up to 19 members could be impacted. Conversely, Republican leadership, including Speaker Mike Johnson, asserts that the judicial rulings restore constitutional fairness by removing racial targets from the process. To counter these shifts, Democratic strategists, including those from the DLCC and House Majority PAC, are pivoting toward a long-term rapprochement with state-level legislative races to secure governing trifectas in states such as Wisconsin, Arizona, and Minnesota, thereby preparing for the 2028 cycle.

利益相關者的定位顯示出策略上的顯著分歧。國會黑人議員 caucus (CBC) 將這些發展描述為民權的系統性退化，主席 Yvette Clarke 估計最多可能有 19 名成員受到影響。相反地，包括議長 Mike Johnson 在內的共和黨領導層則聲稱，司法裁決透過將種族目標從過程中移除，恢復了憲法上的公平。為了應對這些變化，包括來自 DLCC 和 House Majority PAC 的民主黨策略師，正轉向與州級立法競選建立長期協調，以在威斯康辛州、亞利桑那州和明尼蘇達州等州取得執政三權分立 (trifectas)，從而為 2028 年的週期做準備。

Parallel to redistricting, Georgia is experiencing administrative instability regarding voting technology. The state legislature's mandate to ban QR codes by July 2026, driven by claims of systemic vulnerability, has left county election directors without a finalized tabulation method for the midterms. This is compounded by a special session convened by Governor Brian Kemp to address both the QR code transition and the eventual reconfiguration of electoral maps for 2028.

與選區重新劃分平行的是，喬治亞州在投票技術方面正經歷行政不穩定。州立法機關要求在 2026 年 7 月前禁止使用 QR code，理由是系統存在漏洞，導致各縣選舉主任在中期選舉時缺乏最終確定的計票方法。此外，州長 Brian Kemp 召開的特別會議，旨在處理 QR code 轉換以及 2028 年最終的選舉地圖重新配置。

In the upper chamber, the Senate map remains fluid. While Democrats maintain advantages in North Carolina and New Hampshire, races in Ohio, Michigan, and Alaska are classified as tossups. The overall House trajectory, while still favoring a Democratic takeover according to nonpartisan handicappers and prediction markets, has seen a decrease in probability due to the net gain of Republican-leaning districts through mid-decade redistricting.

在上議院中，參議院地圖依然波動。雖然民主黨在北卡羅來納州和新罕布什爾州保持優勢，但俄亥俄州、密西根州和阿拉斯加州的選戰被歸類為不確定結果 (tossups)。整體眾議院的走勢，儘管根據非黨派分析師和預測市場仍傾向於民主黨接管，但由於十年中期的重新劃分導致共和黨傾向的選區淨增加，其獲勝機率已有所下降。

The U.S. legislative map remains in a state of flux as parties utilize judicial precedents and state-level authority to maximize their electoral advantages before the November midterms.

美國的立法地圖仍處於波動狀態，因為各政黨正利用司法先例和州級權限，在 11 月中期選舉前將其選舉優勢最大化。
