When it comes to marijuana, the Elizabeth Warren of 2012 would probably not recognize the Elizabeth Warren of 2019.
Seven years ago, Warren opposed legalization. In 2015, the senator from Massachusetts said she was “open” to it. In 2016, she said, she voted for it privately at the ballot box. Now she’s one of marijuana’s top cheerleaders on Capitol Hill, championing a measure to protect the pot industry in states where it’s legal.
