The 2026 midterm elections handed the Democratic Party majorities in the House and Senate, ending a period of unified Republican control. While the new Congress now holds the legislative levers, President Donald Trump has already signaled an intention to use his veto power to protect key elements of his automotive agenda. This creates a classic split-government scenario where ambitious legislative proposals must survive both bipartisan negotiation and a possible presidential veto.
Two fundamental constraints shape what Democrats can achieve. First, any bill that directly overturns the president’s actions—such as the reinstatement of the $7,500 electric vehicle credit or the repeal of the 25% auto tariffs imposed under Section 232—requires a two-thirds supermajority to override a veto. With only 54 Senate seats secured after the election (and two races still undecided), the Democratic caucus falls well short of the 67 votes needed, even if the remaining contested seats flip their way. Second, many of Trump’s trade measures rest on statutory authority that only the executive can invoke, limiting Congress to oversight, renegotiation of trade agreements, or pressure through the budget process.
Tariffs, trade agreements and congressional oversight
Since assuming office, Trump’s administration has levied a 25% duty on imported vehicles and many parts, invoking a national-security rationale under Section 232. The charge applies to both traditional allies and rival nations, inflating production costs for U.S. manufacturers and adding to the sticker price for consumers. While the Supreme Court struck down an earlier emergency-powers tariff, the Section 232 regime remains legally sound, and the Treasury has already refunded $49.2 billion to affected importers.
Democrats can influence the future of these duties by scrutinizing the United States-Mexico-Canada Agreement (USMCA) and demanding compliance with its rules of origin. Parts that meet USMCA criteria are exempt from the tariff, and a concerted congressional push for a thorough review could restore smoother cross-border supply chains. Moreover, the new majority can summon automakers to testify on how tariff-induced expenses affect employment and investment, a tactic highlighted by law firms advising industry players.
Fuel-economy standards, penalties and the electric-vehicle credit
In the last two years, the Trump administration dismantled the federal framework that enforced fuel-economy standards and eliminated fines for manufacturers missing Corporate Average Fuel Economy (CAFE) targets. The administration also revoked the Environmental Protection Agency’s authority to regulate tailpipe greenhouse-gas emissions and ended the federal tax incentives that made electric vehicles more affordable. These moves were championed as a way to lower vehicle costs, yet industry analysts warn they could stall progress toward higher efficiency and emissions reductions.
Democratic lawmakers are expected to reintroduce the $7,500 electric vehicle credit and push for stricter mileage targets in upcoming CAFE rulemaking. However, any such legislation will again face the veto hurdle, and without Republican votes it cannot become law. The same arithmetic applies to restoring penalties for missed fuel-economy benchmarks; reinstating those fines would require bipartisan support or a successful veto override.
State initiatives and bipartisan security measures
While federal action stalls, Democrats have secured control of key state governments—most notably Michigan and Texas. In Michigan, Governor Jocelyn Benson and a Democratic-led legislature are poised to adopt stronger EV charging mandates and offer state-level incentives, creating a micro-environment where manufacturers can test market-friendly policies. Texas, after flipping the governorship, may also pursue its own EV infrastructure plan, offering a glimpse of how sub-national actions could bypass federal deadlock.
On the security front, a bipartisan bill known as the Connected Vehicle Security Act, co-sponsored by Michigan Senator Elissa Slotkin (D) and Ohio Senator Bernie Moreno (R), seeks to curb the use of Chinese-origin telematics in U.S. vehicles. If passed, the legislation would bar Chinese automakers from selling new cars in the United States, reflecting a rare area of cross-party agreement that could reshape supply chains independent of the tariff debate.
The Democratic majority possesses powerful tools—oversight hearings, trade-agreement reviews, and state-level reforms—to mitigate the economic strain created by Trump’s auto policies. Yet the constitutional reality of a presidential veto and the entrenched statutory basis of the tariffs mean that sweeping reversals remain uncertain. Automakers, investors and consumers will be watching closely as the next two years of congressional negotiation unfold, aware that each policy tweak could ripple through vehicle pricing, fuel costs and the broader shift toward electrification.
