I know Biden tasked the FDA to investigate reclassifying it, which should be a win, but until the FDA actually finishes the reclassification it won't show in the polls. If the bureaucracy can move fast enough for this to get done before the election, it could mean a decent little bump for Biden.
Well, it's already in front of the DEA, and then it goes to a White House committee. Good news there is that Biden would be directly in charge of a White House committee. It apparently took a lot of effort to get the DEA to pull their heads out of their ass, but it's done now (hopefully).
