Why does Obama always refuse to accept any blame for his actions & why does Obama always plead the Sgt Schultz " I know nothing ! " excuse ?

Because it works with the willfully ignorant.

In truth if the subject matter is anything outside of community organizing or golf he is as clueless as they come. 'Uhhh, yes I can't'.

On the day when Obama leaves office, he already has his final excuse ready for the question of why he has done such a poor job as President........................ " answering that question with specificity, you know, is above my pay grade."

This one is real simple. Poor leaders and narcissists are known for not taking responsibility and for blaming others for their mistakes.

Our Boy Barry is from the School of Never Let 'Em See Ya Sweat. He got straight As. When he moved on to the School of Practical Realities, however, and while he called out 'Present!' in homeroom every day, he just hung out with his Choom Gang at the back gate before heading out to bang the gurls during lunch. Such a guy!

i thought obama apologized too much

Yet you cant cite even one example.

I am sure Obama's epitaph on Mount Rushmore will echo your sentiments.

As opposed to all of those republican politicians who always take the blame for their actions and are so honest about everything.
