Obama has failed to take responsibility for the failures on his watch. He blame Bush for the economic wows ,He blames a ill thought out video clip for the failure of foresight over security in Libya..He evades responsibilities on "fast and furious "  ....there is virtually no transparency in his administration .

I think from now and until November we should make the Truman axiom  "The Buck Stops here " a part of the republican battle cry ....
