Biden can't do more. History aside, he has shifted his stance since. However, he is not a dictator.
The solution is pretty simple, really: Vote Democrat; vote out Republicans — then watch Biden be able to pass what has already been introduced by Democrats.
So yes, it really is as simple as, "Democrats are FAR better than Republicans."
After all, when it comes to decriminalization, I can now smoke weed if I want to — thank a Democratic liberal.
