总统唐纳德·特朗普的背书长期以来一直被视作共和党候选人的强大优势，有助于他们争取其政治基本盘的支持，并在竞争激烈的初选中胜出。然而，2026年11月3日中期选举的结果引发了新的疑问：特朗普的支持在普选中是否仍能发挥同样的影响力，因为他支持的几位高知名度共和党人遭遇了失败或陷入苦战。民主党取得进展，特朗普支持的候选人在高关注度竞选中落败特朗普在2026年选举周期中作出了数百项背书，涵盖美国参议院、众议院、州长和州立法机构的竞选。
President Donald Trump's endorsement has long been considered a powerful advantage for Republican candidates, helping them secure support among his political base and navigate contested primary elections. However, the results of the November 3, 2026, midterm elections have raised fresh questions about whether Trump's backing continues to carry the same influence in general elections, as several high-profile Republicans he supported faced defeats or difficult contests. Trump-backed candidates lose high-profile races as Democrats make gainsTrump made hundreds of endorsements during the 2026 election cycle, covering races for the U.S. Senate, House of Representatives, governorships and state legislatures.
据选票百科统计，总统支持的候选人在351场与背书相关的初选中赢得了315场，初选胜率约为96%。然而，初选的胜利并不一定转化为普选的成功，因为在普选中候选人必须吸引更广泛的选民群体。
According to Ballotpedia, candidates backed by the president won 315 of 351 endorsement-related primary contests, giving him a primary success rate of approximately 96%. However, primary victories do not necessarily translate into success in the general election, where candidates must appeal to a much broader electorate.

特朗普将他所支持的几位共和党候选人的败选归因于他们与他的政治运动之间的分歧，暗示部分候选人因反对他而疏远了他的支持者。接受福克斯新闻采访时，特朗普还承认曾支持他个人并不喜欢的候选人，称这样做是为了加强共和党。
“他们不喜欢这些候选人，我支持的有些候选人还和我作对，他们也不喜欢他们和我作对。我的MAGA基础非常强大，”特朗普在接受福克斯新闻采访时说道。
Trump attributed the defeats of several Republican candidates he endorsed to disagreements between them and his political movement, suggesting that some had alienated his supporters by opposing him. Speaking to Fox News, Trump also acknowledged backing certain candidates he personally disliked, saying he had done so in the interest of strengthening the Republican Party.“They didn’t like the candidates, and some of the candidates that I endorsed fought me, and they didn’t like that they fought me. I mean, this MAGA base is incredible,” Trump told Fox News.
