A series of recent U.S. Supreme Court rulings has fundamentally altered the legal framework for congressional redistricting, prompting widespread efforts by state legislatures to redraw electoral maps ahead of the 2026 midterm elections.

近期美國最高法院的一系列裁決從根本上改變了國會選區劃分的法律框架，促使各州議會在 2026 年中期選舉前，大規模地重新劃定選舉地圖。

The current redistricting landscape is primarily predicated on the Supreme Court's decision in Louisiana v. Callais, which significantly narrowed the application of Section 2 of the Voting Rights Act. By ruling that race-conscious districting may constitute an illegal racial gerrymander, the Court has effectively shifted the burden of proof to plaintiffs to demonstrate intentional discrimination. This judicial pivot has facilitated a strategic initiative, encouraged by President Donald Trump, to implement mid-decade redistricting in Republican-led states to secure a more robust House majority. Consequently, states such as Tennessee, Florida, and Alabama have moved to eliminate or consolidate minority-majority districts to favor GOP candidates.

目前的選區劃分格局主要基於最高法院在「路易斯安那州對 Callais 案」中的裁決，該裁決顯著縮小了《投票權法》第二條的適用範圍。法院裁定考慮種族的劃分可能構成非法的種族傑利蠑螈，有效地將舉證責任轉移至原告，要求其證明存在蓄意歧視。這一司法轉向促成了一項在總統川普鼓勵下的戰略計劃，即在共和黨領導的州實施十年中期的選區重劃，以確保眾議院擁有更穩固的多數席位。因此，田納西州、佛羅里達州和阿拉巴馬州等州已採取行動，取消或合併少數族裔佔多數的選區，以利於共和黨候選人。

In Alabama, the Supreme Court vacated a lower court order that had mandated a second majority-Black district, allowing the state to revert to a 2023 map. This action has sparked legal debate regarding the Purcell principle, which generally cautions against altering election rules in close proximity to a vote. Governor Kay Ivey subsequently scheduled special primary elections for affected districts to accommodate the map reversion. Similarly, in South Carolina and Louisiana, legislative efforts are underway to dismantle Democratic-held seats, though some lawmakers express concern that such aggressive redistricting could inadvertently increase the competitiveness of neighboring districts.

在阿拉巴馬州，最高法院撤銷了下級法院要求設立第二個黑人佔多數選區的指令，允許該州恢復使用 2023 年的地圖。此舉引發了關於 Purcell 原則的法律爭論，該原則通常警告不應在選舉臨近時更改選舉規則。州長 Kay Ivey隨後為受影響的選區安排了特別初選，以配合地圖的恢復。同樣地，在南卡羅來納州和路易斯安那州，立法機關正致力於拆解民主黨持有的席位，儘管部分議員擔心如此激進的選區重劃可能會在不經意間增加鄰近選區的競爭力。

Conversely, Democratic strategies have focused on utilizing ballot initiatives and state-level judicial challenges. In Virginia, a voter-approved referendum intended to increase Democratic representation was invalidated by the Virginia Supreme Court. In response, Democratic officials filed an emergency appeal to the U.S. Supreme Court. This appeal invokes the 'independent state legislature doctrine' and argues that the state court misapplied federal law. However, critics characterize this legal maneuver as paradoxical, given the current ideological composition of the federal judiciary. Meanwhile, California has implemented its own voter-approved maps to counterbalance Republican gains in states like Texas.

相反地，民主黨的策略集中於利用公民投票倡議和州級司法挑戰。在維吉尼亞州，一項旨在增加民主黨代表名額且經選民通過的公投被維吉尼亞州最高法院宣布無效。對此，民主黨官員向美國最高法院提交了緊急上訴。此次上訴援引了「獨立州議會學說」，並主張州法院誤用了聯邦法律。然而，批評者認為這種法律手段十分矛盾，考慮到目前聯邦司法體系的意識形態組成。同時，加州實施了其經選民通過的地圖，以抵銷共和黨在德州等州的獲益。

The United States is currently experiencing a period of intense partisan cartographic realignment, where the erosion of federal voting protections has transferred significant power to state legislatures.

美國目前正經歷一段激烈的黨派地圖重新調整期，聯邦投票保障的削弱，將巨大的權力轉移到了州議會。
