Former Vice President Joe Biden hasn’t officially entered the Democratic primary yet. But if he does, he’ll have a lot of explaining to do when it comes to actual policies rather than just talking up his ties to the Obama White House and claims of appeal to the Democratic base. And on marijuana, this is especially evident.

Among the Democrats who have already declared their candidacy and those likely to, Biden is a clear outlier. As the rest of his party clamors to support legalization of recreational marijuana, Biden still seems to be questioning medical marijuana.
