Trump is crazy right? Sessions is a fascist right? Why haven't they unleashed the US Government very aggressively to raid and abuse the states? Who can stop them from doing that? Nobody. They aren't doing it. As far as comparing versus past AG behavior, Sessions is acting like a libertarian (again, by contrast to how things used to be during peak drug war). When California legalized pot for medicinal use, people all up and down the liberal Clinton Administration tried to argue / fight against it. I don't see the Trump Admin doing much of anything toward California (and the rest, DC, Washington, Colorado, et al) on this legalization front.

Sessions once said that he considered the Klan to be OK guys until he found out they smoked weed. He can't go fully anti-weed until Rohrabacher-Farr is undone by Congress, and he has been vigorously asking Congress to do so. Why would he campaign against it, unless he intended to immediately instruct DoJ and DEA to act against states who have made it legal? He has made it absolutely clear that he doesn't just intend to go after recreational weed, but medical as well. Libertarian? I do not want whatever you're smoking.
