William F. Buckley, Jr.
From Wikipedia (numbers cite references on Wikipedia page)
Buckley was an advocate for the legalization of marijuana and some drug legalization as early as his 1965 candidacy for mayor of New York City. He wrote a pointed pro-marijuana legalization piece for National Review in 2004 where he calls for conservatives to change their views on legalization, stating, “We’re not going to find someone running for president who advocates reform of those laws. What is required is a genuine republican groundswell. It is happening, but ever so gradually. Two of every five Americans […] believe ‘the government should treat marijuana more or less the same way it treats alcohol: It should regulate it, control it, tax it, and make it illegal only for children.'”
