Why would Republican Presidents support high Tariffs?

Republican Presidents often support high tariffs as a means to protect domestic industries and jobs from foreign competition, aiming to bolster the economy and promote American manufacturing. Tariffs can stimulate local production by making imported goods more expensive, encouraging consumers to buy domestic products. Additionally, high tariffs can generate government revenue and serve as a tool for negotiating trade deals. This approach aligns with the Republican emphasis on free enterprise and economic nationalism.
