I know what that is
It's not surprising, he's was running to be President, he has done a lot of things along the way to cover his own ass, which is very smart. By choosing to support marijuana legalization he would be alienating too many people, and he can't and won't do that.
In the end, he's just trying to keep his job and he's smart enough to know when to keep his mouth shut and on what issues.
Marijuana legalization is a very contrevercal subject, and while I support it 100%, I'm not a big name politician, and if I was, with the control and people being how they are, I can't say that I would be supporting the legalization of it at this time either. Who knows, he may make a lot of changes and he's in a position to educate a mass amount of people, I would be taking advantage of that situation and educating people, but until a change in the social conscisousness changes from that of MJ being horrible and danger to it being helpful and having a medical purpose, that's when it will be legalized. Until then, it just ain't happening.
Plus, Obama has so MUCH bigger fish to fry right now, let him do that and see if he's successful, if he is and gets elected to a second term, bother him about it then, more likely to get something done.
