Here's another case where elections matter. In an interview with Barbara Walters this morning he said, "'It does not make sense from a prioritization point of view' to focus on drug use in states where it is now legal."
It's not the ringing endorsement of legality that people might like, but when you're asked if you would make pot legal and you answer, "I wouldn't go that far," that's a case where you can evolve more on the issue over the course of his term. It's just a start, but it is indeed a start. Keep pushing and let's see where this will go.
