Tariffs have emerged as possibly the defining aspect of Donald Trump's presidency and they're poised to make life a lot harder.

Mr. Trump's claim about tariffs lowering taxes amounts to "an argument that says, 'If Americans pay more out of their left pocket, the government will be able to put more in their right pocket,'" said Joe Rosenberg, senior fellow at the Urban-Brookings Tax Policy Center, another think tank focused on taxes.

To the extent Trump’s tariffs are a “negotiating strategy,” as Treasury Secretary Scott Bessent has claimed, are critics missing that they are simply part of the “art of the deal” that will enable America to gain coercive leverage over other states?

Republicans typically love President Trump — no matter what he does. But a growing chorus of those supporters has quietly been expressing dissatisfaction with Trump’s handling of tariffs, including his most recent threat on foreign-made films.
