Senator JD Vance's emphasis on protectionist economic policies, particularly tariffs, is proving detrimental to the Republican Party's standing with voters, according to an opinion piece in The New York Post. The article argues that this approach, a core tenet of the "National Conservative" movement Vance champions, is deeply unpopular and risks long-term damage to the GOP's economic agenda.

The author contrasts the economic sentiment during President Trump's first term with his second. In Trump's first term, economic confidence was reportedly strong, even with lower personal approval ratings for the president. However, the piece claims that by December 2025, economic confidence had fallen significantly, a trend exacerbated by post-COVID inflation and further worsened by the implementation of broad tariffs early in Trump's second term. This shift, the article asserts, is largely attributable to Vance's influence.

The New York Post piece highlights that Trump's first term was characterized by deregulation and tax cuts, with protectionist measures being limited. The Tax Cuts and Jobs Act, for instance, is cited for significantly lowering corporate and individual tax rates. In contrast, the article describes the initial economic policy of Trump's second term as the unilateral imposition of tariffs on goods from numerous countries, enacted without broad congressional or electoral consensus.

Protectionism, the author contends, has led to "red tape, corruption, corporate rent-seeking and chaos," all under the guise of a "fake emergency." Public opinion data is cited to suggest that Trump's approval ratings declined sharply following the announcement and subsequent implementation of these tariffs. Exit polls allegedly indicate that a significant majority of Americans believe tariffs harm the economy, with this sentiment prevalent across various regions and demographics, including working-class voters and trade-dependent states like Texas, Ohio, and Michigan.

The article draws a parallel between the public's reaction to protectionism and the initial support for policies like "Medicare for All." While voters may initially be drawn to promises of bringing back jobs and revitalizing industries, the real-time experience of protectionist policies appears to lead to a rapid disillusionment.

The piece concludes that the "national conservatives," led by figures like Vance, have captured key institutions within the GOP and are shifting fiscal policies to appeal to a narrow segment of voters at the expense of others. The author suggests that if Republicans continue down a path of wealth redistribution, increased government spending, and punishing corporations, they risk alienating voters who may find alternative parties better suited to such agendas. Vance's brand of economic policy, described as "warmed-over progressivism," is presented as having little future within the Republican Party.
