Oregon Rep. Earl Blumenauer, one of Congress’s most vocal marijuana proponents, sent Democratic leadership a memo Wednesday outlining steps Congress should take to legalize the Schedule I drug.

“Congress is out of step with the American people and the states on cannabis,” Blumenauer wrote in the memo, citing polling showing that 69 percent of registered voters support legalizing marijuana. “We have an opportunity to correct course if Democrats win big in November.”

The founder of the Congressional Cannabis Caucus said there is no question that the federal marijuana prohibition will end and that Democrats should lead the way or lose the issue.

“If we fail to act swiftly, I fear as the 2020 election approaches, Donald Trump will claim credit for our work in an effort to shore up support — especially from young voters,” Blumenauer said. “Democrats must seize the moment.”

Congress needs to enact legislation softening the federal stance on marijuana by the end of 2019, he argued, offering Democratic leadership a blueprint on actions they should take over the course of next year.
