David Arthur Keene, a towering figure in American conservative politics, passed away on March 8, 2026, in Baltimore, Maryland, at the age of 80, after a battle with pancreatic cancer. Keene's extensive career spanned decades, leaving an indelible mark on the conservative movement through his roles as a political consultant, presidential advisor, and influential organizational leader.

Born on May 20, 1945, in Rockford, Illinois, Keene was raised in Fort Atkinson, Wisconsin. He developed an early passion for political engagement, becoming the national chairman of Young Americans for Freedom (YAF) during his time at the University of Wisconsin in the 1960s.

Keene's journey into national politics began with his service as a political assistant to Vice President Spiro Agnew during the Nixon administration. He later served as executive assistant to Senator James L. Buckley in the 1970s, gaining valuable experience in the corridors of power.

His strategic acumen was highly sought after in presidential campaigns. Keene served as the southern regional coordinator for Ronald Reagan's 1976 presidential bid and later as the national political director for George H. W. Bush's 1980 presidential campaign. He also advised Senator Robert Dole's presidential campaigns in 1988 and 1996.

Perhaps one of his most significant contributions was his nearly three-decade tenure as chairman of the American Conservative Union (ACU) from 1984 to 2011. Under his leadership, the Conservative Political Action Conference (CPAC) transformed from a modest gathering into a premier annual event for conservatives, attracting thousands of activists and prominent political figures.

Following his impactful role at the ACU, Keene served as the president of the National Rifle Association of America (NRA) for two one-year terms from 2011 to 2013. He was a staunch advocate for gun rights and was appointed by the Bush White House as a public delegate to the UN Small Arms and Light Weapons Conference.

In 2013, Keene transitioned to a prominent media role, becoming the opinion editor of The Washington Times, and later serving as editor at large. He also co-founded the American Freedom Agenda (AFA) in 2007, an organization dedicated to restoring checks and balances and civil liberties protections.

David Arthur Keene's legacy is that of a dedicated conservative leader who shaped political discourse, mentored countless individuals, and championed principles he deeply believed in. His influence extended from grassroots activism to the highest levels of government, leaving an enduring impact on the American political landscape.
