Per Panetta's comments, the intel was actually gained from multiple sources, of which "enhanced interrogation" was one. That said, I'm not sure why you think whoever is in office deserves "all the credit." In my view, that is a problem with the way we view politics. The fact is, any President in office would have instructed the intelligence brass to make a top priority to find and neutralize OBL. That part of it was a no brainer. It was the people on the ground, gathering information, who really deserve the cred.
Similarly, we tend to blame whoever is currently in office for all mistakes on the ground, so it does go both ways. And it's often a fallacy whether it is a matter of either credit or blame.
