Waldman doesn't expect Obama to end the Drug War:
While Obama may believe that the War has been a failure and it's absurd to lock up hundreds of thousands of people for possessing, buying, or selling small amounts of marijuana, it just isn't all that high on his priority list. If making a major policy change is risky, he's not going to bother. On the other hand, he doesn't want to alienate the 50 percent of the country that now supports legalization, many of whom are his staunch supporters, so his preferred outcome would be that no one pays much attention to the issue for the next four years.
Along those lines, Mike Riggs noted a few days ago Obama still hasn't publicly discussed the Washington or Colorado legalization laws. Reader thoughts on the subject here.
