Right Wing World: Obama Responsible for Everything Bad, Nothing Good

I realize that FreeRepublic.com isn't a place you go if you want internal consistency. But I have to share this quote from a FReeper named mardi59 today, during the President's speech on drones and Guantanamo Bay:

"He is trying to fight the scandals by now acting like he knows what he’s doing. He is a miserable failure. All he knows how to do is spike the football and take credit for what others have done. He’s a joke."

If you parse that, you'll see that President Obama is responsible for the State Department's decision making in Benghazi, the Justice Department's actions with the AP and the IRS's internal policymaking on the Tea Party affair. He should've been on top of all of these issues, and has instead been absent and/or bad at his job.

However, in the second part of that quote, Obama's not apparently supposed to take credit for what "others" have done that has turned out well. So, which is it? Is the President responsible for all the agencies and divisions of the government he oversees, or is he not?
