William McKinley and Donald Trump display striking similarities in their leadership styles and policies, despite existing in different eras. Both faced assassination attempts, with McKinley killed in 1901 and Trump surviving two threats. Their economic strategies involved protectionism; McKinley raised tariffs through the Dingley Tariff Act, while Trump imposed tariffs on steel and aluminum. Nationalism characterized both presidencies, with McKinley promoting American exceptionalism and Trump emphasizing “America First.” Immigration policies also reflect this trend; McKinley sought stricter laws, and Trump enacted travel bans and the “Remain in Mexico” policy. Their business backgrounds influenced governance, intertwining economic prosperity with national priorities.
