特朗普在密歇根州通用汽车工厂集会上为其关税政策进行宣传，声称汽车公司因此"表现得比以往任何时候都好"[1]。然而，关税政策已经对美国企业造成了实质性冲击。密歇根州自特朗普2024年4月宣布"解放日"关税以来，已失去8,300个制造业工作岗位（截至去年同月），汽车零部件制造业工作岗位与去年同期相比下降约4,000个[1]。
尽管一些企业宣布了新的投资举措，但这些举措的时间跨度较长。通用汽车宣布2025年6月投资40亿美元将部分车辆生产从墨西哥转移至美国，丰田则宣布投资36亿美元将Tacoma皮卡生产从墨西哥搬迁至德州，但这一过程耗时约四年[1]。与此同时，特朗普政府计划对加拿大进口商品征收50%的关税[1]。
虽然许多特朗普的支持者继续拥护其政策，但他们对关税带来的短期经济痛苦和高物价感到担忧[1]。特朗普的集会恰逢密歇根州下周二举行初选，他正支持众议员约翰·詹姆斯参加州长初选[1]。
Former President Donald Trump rallied support for his tariff policies at a General Motors facility in Milford, Michigan, claiming that automakers are performing better than ever due to his trade actions [1]. However, the economic reality presents a more complicated picture, with tariffs having cost American businesses billions of dollars while intensifying inflationary pressures [1].
Michigan has experienced particular strain from Trump's trade policies since he announced what he called "Liberation Day" tariffs in April 2024, losing approximately 8,300 manufacturing jobs in the state as of the same month the following year [1]. Automotive parts manufacturing employment in Michigan has declined by roughly 4,000 positions compared to the prior year [1]. Despite these headwinds, some companies have announced major investments in American production: General Motors plans to invest $4 billion in June 2025 to shift certain vehicle production from Mexico to the United States, while Toyota announced a $3.6 billion investment to relocate Tacoma pickup production from Mexico to Texas, a transition expected to take approximately four years [1].
Trump's tariff agenda faces legal obstacles as well. The Supreme Court has struck down numerous tariffs that Trump had ordered upon his return to the White House [1]. His administration continues to pursue aggressive trade measures, including plans to impose a 50 percent tariff on Canadian imports [1].
While Trump's supporters in Michigan remain largely aligned with him, many express concern about elevated prices and the near-term economic hardship stemming from tariff policies [1]. The state will hold its primary election the following Tuesday, with Trump backing Representative John James in the gubernatorial primary [1].
