VERIFIED SOURCING CORRECTION: the prior rating attributed this line to a Sept. 24, 2024 Savannah, Georgia speech. It is verifiably from Trump's RNC acceptance speech of July 18, 2024 (confirmed verbatim in the LiveNOW from FOX full transcript, and matching the dateMade 2024-07-18 already stored in StumpWatch's own data/promises/trump-2016-2024.json). The speech context is Chinese-owned auto plants under construction in Mexico intended to export cars into the U.S. The substance of the prior rating survives re-checking. WHAT WAS DELIVERED: Trump personally drove a real, new auto-tariff regime by executive action -- Proclamation 10908 (signed Mar. 26, 2025; Federal Register Apr. 3, 2025) imposed a 25 percent Section 232 tariff on imported automobiles, and Proclamation 10925 (May 2, 2025) added a U.S.-assembly import adjustment offset expressly framed as a way to 'shift manufacturing activity into the United States,' i.e. the promise's stated purpose ('the way they will sell their product in America is to build it in America'). WHAT WAS NOT DELIVERED: the promised magnitude. The rate is 25 percent, not 100-200 percent, roughly a quarter of the low end of the promise, and imported cars plainly remained sellable. Verified current as of the Tax Foundation tariff tracker last updated May 21, 2026: the Section 232 auto rate is still 25 percent general, with NEGOTIATED REDUCTIONS moving away from the promise -- UK 10 percent on the first 100,000 vehicles (May 8, 2025), EU 15 percent (Aug. 21, 2025), Japan 15 percent (Sept. 16, 2025) -- plus a U.S.-content carve-out for USMCA (Canada/Mexico) imports written into Proclamation 10908 itself, which directly softens the treatment of the Mexico-built vehicles the promise singled out. A Federal Register presidential-documents query returned zero new automobile/auto-parts tariff proclamations after Nov. 2025, and no auto tariff has ever reached 100 percent. Notably Trump DID go to 100 percent for patented pharmaceuticals (Apr. 2, 2026), showing the 100 percent tool was available and simply was not applied to cars. ADVERSARIAL CROSS-CHECK ON THE LABEL: CHAMPIONED (+0.75) was considered because Trump unilaterally led this himself, but CHAMPIONED is for an effort that did not land; this one landed, just at reduced magnitude, and he subsequently bargained the rate DOWN for the UK, EU and Japan. ATTEMPTED (+0.25) understates it, since a binding tariff regime is in force. Applied party-neutrally: an officeholder of either party who promised a 100-200 percent tariff, delivered 25 percent by their own hand, and then cut it to 10-15 percent for major trading partners would be scored 'kept some but not all of it.' PARTIAL stands. One caveat noted for fairness rather than credit: Chinese-built vehicles are effectively unsellable in the U.S., but that stems from the Section 301 100 percent EV tariff finalized under the prior administration in Sept. 2024, not from this promise-keeper's action, so it is not counted toward fulfillment.
