LOS ANGELES - As campaign stops for Republican presidential candidates go, the International Drug Policy Reform Conference in downtown Los Angeles seemed like a strange choice.
There was reggae music booming from big speakers, lapel pins shaped like marijuana leaves, and a speech by California Lt. Gov. Gavin Newsom, the liberal former mayor of San Francisco who is famous for granting marriage licenses to same-sex couples.
Yet there Gary Johnson stood last month, drawing cheers from a crowd of drug decriminalization activists.
Johnson, former governor of New Mexico, has promised that if he wins the Republican nomination and is elected president, he'll issue a pardon for anyone serving prison time for a nonviolent marijuana crime. He has also pledged to overhaul the tax system and cut federal spending by 43 percent.
