If you’re looking for convincing arguments; read through the responses from this panel of experts: https://www.kentclarkcenter.org/surveys/tariffs/ (from 2024) and more recently: https://www.kentclarkcenter.org/surveys/tariffs-reciprocal-and-retaliatory-2/

Many of the responding professors provide detail on why they vote a certain way. For example to the 3rd part of the question from 2024: “The gains for the American economy from tripling the tariffs would measurably outweigh the losses.” you get replies like:

Protectionism via tariffs creates well-understood aggregate losses in efficiency. This is so even if China “unfairly” subsidizes its steel. Political motivations aside, actual distributional impacts are modest, ill targeted, and better handled with other more direct tax tools.

Not sure if this will convince you or not; but it’s at least a cache of relevant information.

First quarter was before tariffs were announced?

Republicans are so dumb :(
