He has never been in the private sector or the military, or accomplished anything in the public sector short of getting himself elected to an escalating snowball of offices simply for being Barack Obama. He did nothing as a state senator, or a US senator and other than double the debt and accrete power to a listless and bloated government, he did nothing in the paltry few weeks he was President before being nominated for this ignoble Peace Prize.
Of course, he need not actually do anything really, since the man claims his own existence as an inspiration to the world.
