John David McAfee was a British-American computer programmer, businessman, and two-time presidential candidate who unsuccessfully sought the Libertarian Party nomination for president of the United States in 2016 and in 2020. In 1987, he wrote the first commercial anti-virus software, founding McAfee Associates to sell his creation. He resigned in 1994 and sold his remaining stake in the company. McAfee became the company's most vocal critic in later years, urging consumers to uninstall the company's anti-virus software, which he characterized as bloatware. He disavowed the company's continued use of his name in branding, a practice that has persisted in spite of a short-lived corporate rebrand attempt under Intel ownership.

The 2016 Libertarian National Convention was the gathering at which delegates of the Libertarian Party chose the party's nominees for president and vice president in the 2016 national election. The party selected Gary Johnson, a former Governor of New Mexico, as its presidential candidate, with Bill Weld, a former Governor of Massachusetts as his running mate. The convention was held from May 26–30, 2016, in Orlando, Florida.
