特拉华州举行闭门初选 2026全美中期选举初选季正式收官Delaware Holds Closed Primaries as 2026 Midterm Nomination Season Concludes

特拉华州法律规定，大选年的州及地方初选在9月第一个星期一之后的第二个星期二举行，这一时间设置让该州的投票日期排在2026年9月的第三周，成为全美中期选举周期的最后一场州级初选。该州采用严格的闭门初选规则，仅限登记在册的民主党和共和党选民参与各自党派内部的提名竞争。此外，州法规定仅在单个党派内出现多名参选人时才举行初选投票，无党内竞争的候选人自动晋级11月3日的普选。

Delaware state law dictates that state and local primary elections take place on the second Tuesday following the first Monday in September during general election years, situating the contest in the third week of September as the final state primary of the 2026 midterm cycle. Under Delaware's closed primary rules, only registered Democrats can cast ballots in the Democratic primary, and only registered Republicans can vote in the Republican primary. State regulations also establish that primary elections are conducted solely for offices where more than one candidate from the same party is running, allowing uncontested contenders to advance directly to the general election on November 3.

特拉华州选民结构在过去数十年间呈现鲜明的民主党主导特征。根据州选举记录，自1990年代以来该州政治版图持续向民主党倾斜，共和党自1988年起未曾赢得过州长选举，自1994年起未曾赢得过联邦参议院席位，自2008年起亦未曾赢得过联邦众议院席位。截至2026年9月1日，特拉华州约80.8万名登记选民中，民主党人约占33.1万，共和党人约占19.9万，庞大的登记优势构成了两党在州级与联邦公职竞争中的核心基本盘。

The electoral landscape in Delaware has leaned heavily Democratic since the 1990s, with Republicans failing to win the governor's office since 1988, a U.S. Senate seat since 1994, or the state's lone U.S. House seat since 2008. As of September 1, 2026, the state's approximately 808,000 registered voters included roughly 331,000 registered Democrats compared to about 199,000 registered Republicans, establishing a substantial registration advantage for Democratic nominees heading into the fall campaign.

在联邦参议院席位角逐中，现任民主党籍联邦参议员克里斯·库恩斯正寻求其第三个完整任期。库恩斯自2010年通过特别选举填补乔·拜登就任副总统后留下的空缺以来一直担任该职。竞选财务数据显示，库恩斯为连任筹集了超过680万美元，而其主要竞争对手仅筹得15万美元，另外两名挑战者则未报告任何筹款，资金差距极为显著。

In the race for the U.S. Senate, incumbent Democratic Senator Chris Coons is seeking a third full term after first winning the seat in a 2010 special election to succeed Joe Biden following his ascension to the vice presidency. Coons entered the primary contest with an overwhelming financial lead, raising more than $6.8 million for his reelection campaign compared to $150,000 reported by his closest primary rival, while the remaining two challengers reported no fundraising at all.

库恩斯在民主党初选中面临三名党内对手，包括特拉华大学历史学教授杰夫·阿佩尔汉斯、造船工程师玛丽·卢夫，以及前企业高管埃里克·汉森。汉森曾在2024年作为共和党候选人参选联邦参议员，转投民主党后在选票上登记为“E. 反特朗普·汉森”（E. No-Trump Hansen）。共和党方面，前州参议员迈克尔·卡茨与美国陆军预备役上校约翰·舒利展开初选竞争，胜者将在11月普选中挑战民主党提名人。

Three Democratic opponents appeared on the primary ballot against Coons: University of Delaware history professor Jeff Appelhans, naval architect Mary Louve, and former business executive Eric Hansen. Hansen, who ran as the Republican nominee for the U.S. Senate in 2024, switched his affiliation to the Democratic Party and filed to run under the ballot name 'E. No-Trump Hansen.' On the Republican side, former state Senator Michael Katz and U.S. Army Reserve Colonel John Shulli competed in their party's primary to determine who will advance to face the Democratic nominee in November.

在特拉华州唯一的联邦众议院全州席位竞争中，民主党籍现任众议员萨拉·麦克布莱德在党内初选中没有任何挑战者，依州法直接锁定提名晋级11月大选。麦克布莱德是美国历史上首位公开跨性别身份的国会议员。自2024年底进入国会前夕起，她便成为共和党议员关注的焦点。当时众议院议长迈克·约翰逊宣布议员须使用与其生理性别对应的卫生间，提出该规定的共和党众议员南希·梅斯称此举针对麦克布莱德。麦克布莱德随后发表声明表示将遵守规则，并指出此类举措旨在转移公众对国家实际问题的关注。

In the contest for Delaware's sole at-large seat in the U.S. House of Representatives, incumbent Democratic Representative Sarah McBride faced no primary challengers and advanced uncontested to the November general election under state rules. McBride, the first openly transgender member of Congress, became a focal point among congressional Republicans leading into her first term. In November 2024, prior to her arrival on Capitol Hill, House Speaker Mike Johnson announced that members must use restrooms corresponding to their biological sex, following a ban introduced by Republican Representative Nancy Mace that was aimed at McBride. McBride stated at the time that she would comply with the directive while asserting it was designed to distract from real issues.

共和党方面，三名参选人参与初选以争取在11月普选中对阵麦克布莱德，竞争者包括约瑟夫·阿尔米尼奥、改投共和党的前2024年民主党初选对手厄尔·库珀，以及2024年大选共和党候选人约翰·惠伦。由于民主党自2010年以来一直牢固控制着该众议院席位，无论共和党由谁胜出，麦克布莱德在秋季决选中仍被外界视为占据明显优势。

On the Republican side, three candidates entered the primary to compete for the nomination to face McBride in the general election: Joseph Arminio, Earl Cooper, and John Whalen III. Cooper had previously challenged McBride in the 2024 Democratic primary before switching parties, while Whalen ran as the Republican nominee in the 2024 general election. With Democrats holding this at-large seat uninterrupted since 2010, McBride is widely favored heading into the November contest.

特拉华州的初选投票结束了2026年全美中期选举的党内提名阶段。在民主党内部，左翼与美国民主社会主义者（DSA）支持的参选人在多个州击败了长任期建制派对手。6月，科罗拉多州15任资深众议员戴安娜·德盖特被梅拉特·基罗斯击败，纽约州5任众议员阿德里亚诺·埃斯帕利亚特亦被达莉亚莉扎·阿维拉·谢瓦利埃拉下马。8月，阿卜杜勒·埃尔-萨耶德在密歇根州、佩吉·弗拉纳根在明尼苏达州以及安吉·尼克松在佛罗里达州分别斩获关键全州参议院初选胜绩。许多胜选者主张废除移民和海关执法局、削减对以色列军事援助并推行全民医保。

The Delaware primary formally concludes the nomination phase of the 2026 midterm election cycle, capping months of competitive intraparty contests nationwide. Within the Democratic Party, left-wing contenders backed by the Democratic Socialists of America secured high-profile victories over long-serving establishment figures. In June, 15-term incumbent Representative Diana DeGette of Colorado was ousted by Melat Kiros, while five-term Representative Adriano Espaillat of New York was defeated by Darializa Avila Chevalier. Progressive momentum expanded in August with statewide Senate primary wins by Abdul El-Sayed in Michigan, Lieutenant Governor Peggy Flanagan in Minnesota, and state Representative Angie Nixon in Florida, running on platforms calling for single-payer health care, the abolition of ICE, and cuts to military aid to Israel.

共和党方面，唐纳德·特朗普继续展示其对党内初选的强劲主导力。根据媒体的背书追踪数据，特朗普本选举周期在共和党参议院初选中的背书实现全胜，在众议院初选中也保持近乎全胜的战绩，尽管其支持的参选人在五场共和党州长初选中遭遇失利。特朗普于8月下旬发文宣称其背书影响力达到历史顶峰，其民粹主义与“美国优先”路线进一步巩固了在党内初选中的号召力。

Across Republican primaries, Donald Trump maintained a dominant endorsement record throughout the cycle, despite setbacks where five of his preferred candidates lost in gubernatorial races. According to tracking data, Trump achieved a flawless record in Senate Republican primaries and a near-perfect run in House contests. Trump touted on social media in late August that his endorsements were stronger than ever, reflecting the persistent influence of his populist America First movement in deciding GOP congressional nominations heading into the general election.
