The opposite of omniscient would be omni-inscient or omninscient. A little too difficult to distinguish. I would suggest omnimoronic or obamoronic. The latter could be the standard terminology for incredibly all-encompassing political stupidity a century from now.
His assembly of the doctors outside the WH yesterday looked “obamoronic”. I think it was about the dumbest photo-op I’ve seen since Dukakis rode in the Army tank. The “doctors” all dressed in their lab coats outside the White House waiting for the “One”. He then emerges, walks to the teleprompter and starts reading. Obamoronic is a great word to describe it.
