By this logic, if the gun control measures fail to pass Congress it should be the President's fault?
What I'm saying is nobody will blame his lack of effort. And, if history is any indication, he or his successors will keep trying until they do pass.
Nobody can say the President isn't trying hard enough in those cases, whichever side of the fence you happen to fall on. Yet, when we talk about basic human rights, the President somehow gets to just give up on the issue, and we should be OK with that? In my opinion, there is definitely a lack of effort by the President to do something about closing Gitmo, and I find that almost as disappointing as Gitmo being opened in the first place.
