Reason has an interesting piece looking at the various candidates, past and present, to support significant marijuana law reform:
Three days after Bernie Sanders unveiled legislation to repeal the federal ban on marijuana, Hillary Clinton proposed moving marijuana to a slightly less restrictive legal category. The former secretary of state’s faint echo of the Vermont senator’s bold bill—the first of its kind in the Senate—underlined how timid Clinton has always been on the subject of drug policy reform. Although the presumptive Democratic presidential nominee has had second thoughts about the mandatory minimum sentences she used to champion, the woman who a few years ago explained that we can’t legalize the drug trade because “there is just too much money in it” clearly is not ready to call off the war on weed, even though that is what most Americans seem to want.
The dueling marijuana proposals also showed that Sanders, whose chances of winning his party’s presidential nomination are remote at best, is nevertheless pushing Clinton to address issues she would prefer to ignore.
The article covers a variety of candidates, past and present, in addition to Sanders and Clinton, including Mike Gravel, Gary Johnson, Dennis Kucinich, Ron Paul, and Rand Paul.
