Not long ago, Gary Johnson, the Libertarian Party’s 2016 Presidential candidate, put a halt to his considerable consumption of marijuana. “The last time I indulged is about two months ago, with some edibles,” Johnson told me in late June, in the lobby of a midtown hotel. Johnson, who was the Republican governor of New Mexico from 1995 to 2003, also ran for President in 2012, as a Libertarian, and received just under one per cent of the vote, but he believes this year could be different. At the end of May, William F. Weld, the former moderate Republican governor of Massachusetts, became the Libertarian Party’s Vice-Presidential nominee, giving the Party its most mainstream ticket since its founding, in 1971.
