The Libertarian Party is deeply saddened to share that longtime activist, candidate, and former national staff member David Aitken passed away on May 28 at the age of 79.

David was a foundational pillar of the liberty movement in Colorado for four decades. A U.S. Army veteran (1967–1971) and retired business software developer, he dedicated his life to advancing individual freedom. Whenever the movement needed a standard-bearer, David answered the call—serving as Colorado LP Chair, defending petition rights in court, and running for numerous offices including Governor (1990), Secretary of State (2002), and State Senate (2024).

Inspired by the economics of Milton Friedman and Thomas Sowell, David’s core mission was to reduce government regulation so everyone could freely pursue their dreams. When he wasn’t fighting for freedom, he could be found enjoying his retirement on Capitol Hill or skiing at Copper Mountain.

We are profoundly grateful for David’s lifetime of tireless service. Our deepest condolences go out to his family, friends, and the many liberty lovers whose lives he touched. Rest in peace, David.
