Is he competent?

[mpholland]

I have never been a big Obama fan, but thought that maybe he would at least try to do his best. Now with Fast and Furious, Benghazi, the IRS, the AP scandals I suppose for lack of a better term, is Obama seeming a somewhat incompetent? His answer for all of them seems to be "I didn't know". How can the person with access to more intelligence than any other man in the world not have a clue? If he really didn't know, then I find that a serious competency issue. Aren't the chief executives ultimately to be responsible for subordinates?
Just curious about peoples thoughts here.
