President Donald Trump’s reinvigorated focus on tariffs and aggressive trade measures is encountering skepticism within his own voter base, according to a new poll conducted by Politico and Public First in June 2025. As the administration prepares to enact a new round of tariffs on August 1—including a threatened 30% levy on imports from Mexico and the European Union—supporters who helped bring Trump back to the White House in 2024 are showing growing unease about the real-world consequences of these policies.

Polling Reveals Supporters’ Doubts Amid Tariff Escalation

The June poll found that between a quarter and nearly half of self-identified Trump voters expressed concerns about the president’s latest round of tariff policies, particularly as they relate to ongoing trade tensions with China. While tariffs have been touted by the Trump administration as a means to protect American industries and rebuild manufacturing at home, only about half of the president’s supporters believe these measures will in fact benefit US companies.

The skepticism comes as President Trump has redoubled efforts on trade-related issues, sending contentious letters to leaders of key trading partners and outlining plans for sweeping new tariffs. Some of these measures, such as the threatened 30% tariff rate on goods from the EU and Mexico, would mark some of the most significant hikes in modern American economic history.

Many in the president’s base are split not only on the likely outcomes of these tariffs, but also on the fundamental question of executive authority: 44% of respondents say that Trump should require Congressional approval for tariff impositions, while 45% believe the president should have unilateral authority to levy import taxes.

Economic Impact and Voter Anxiety

For years, Trump has contended that aggressive tariffs are essential to restoring US economic vitality and protecting American workers from what he terms “unfair foreign trade practices.” Yet, the poll shows that 25% of his own voters now believe tariffs may be hindering the US in its ability to negotiate better trade deals, and even harming domestic business competitiveness.

The imposition of tariffs is rarely a one-sided affair. Economists from the Peterson Institute for International Economics and other think tanks warn that while tariffs may benefit targeted industries in the short term, the costs are typically passed onto US consumers in the form of higher prices. Over the past year, as the US-China trade dispute escalated, prices on electronics, household goods, and key manufacturing inputs have increased—trends reflected in the most recent government inflation data for 2025.

When asked specifically about tariffs on China, 46% of Trump voters said they supported these measures even if it meant higher domestic prices. However, 32% expressed support only if tariffs did not increase costs for Americans, and 9% said they were outright opposed. Notably, 25% said the China-specific tariffs were hurting US companies.

Trump Administration’s Rationale and Broader Trade Trends

The White House has remained publicly resolute. President Trump argues that increased tariffs are necessary to force concessions from trading partners, rebalance trade deficits, and deter what he claims are predatory practices by China and other manufacturing powerhouses. Administration officials point to recent job growth in select manufacturing sectors, though economists caution that the US remains locked in a fragile global supply chain system increasingly vulnerable to trade disruptions.

China, for its part, has responded in kind, instituting its own counter-tariffs on US agricultural products, technology goods, and energy exports. A July 2025 policy note from the WTO indicates global trade growth for the year is now forecast at just 1.3%, down from previous expectations, with economists citing “persistent uncertainties due to US tariff escalation and retaliatory actions by major economies.”

In light of this, business leaders across sectors have sounded alarms about tariff-induced volatility. The US Chamber of Commerce recently issued a statement cautioning that “continued tariff expansion risks undermining US competitiveness, raising consumer prices, and jeopardizing export markets for key American industries.”

Tariffs, Partisanship, and the 2026 Election Cycle

While divided over specifics, a slim majority of Trump voters—55%—say they expect the president will ultimately be able to negotiate a favorable trade pact with China, though 18% doubt the difficulty and 12% expect failure. Among 2024 Kamala Harris voters surveyed, a striking 86% believe Trump’s tariffs are damaging US trade relations, reflecting the significant partisan divide in perceptions of the policy’s effectiveness.

As presidential politics gear up for the 2026 midterm cycle, analysts say trade and tariff policy are shaping up as central themes—not just in national headlines, but on the campaign trail. While Trump seeks to frame tariffs as a symbol of “America First” resolve, his advisers have been privately urged by supporters and industry stakeholders to weigh potential blowback associated with higher consumer costs and diminished export opportunities.

The poll’s findings reflect a wider reality: in today’s interconnected global economy, even hardline trade measures billed as a boon for US workers can carry complex consequences, creating rifts not just with other nations, but within a president’s own political coalition—a challenge that may ultimately shape both economic outcomes and electoral fate.
