Assassination Attempts on U.S. Presidents and Presidential Candidates

Overview

Throughout American history, numerous assassination attempts have been made on sitting presidents, former presidents, and presidential candidates. While some were thwarted, others resulted in injury or long-term political consequences. This section documents these attempts, providing critical context and details.

Common Themes

Mental Illness
Several assailants were later found to be suffering from psychological disorders, including Lawrence, Hinckley, and Schrank.

Political Extremism
Ideologically motivated attacks—from Puerto Rican nationalists to white supremacists—recur throughout history.

Candidate Vulnerability
Campaign trail security is consistently weaker than presidential protection, making candidates especially vulnerable.

Impact and Legacy

Though not all attempts were successful, each has played a role in shaping presidential security, public perceptions of political violence, and the evolution of Secret Service protocols. The threat of assassination remains a persistent concern for those who seek or hold the highest office in the United States.
