But some of his potential picks for top administration jobs might come as a surprise. Obama is weighing an array of Washington insiders and outsiders -- including some Republicans -- for top administration posts, according to Democratic officials. Obama has signaled that he will make no Cabinet-level appointments immediately, and his deliberations are tightly held by his closest aides. But that hasn't stopped Democrats and interest groups from circulating lists and offering recommendations to the Obama transition team. Some are surprising, such as former Bush Secretary of State Colin Powell as possible education secretary. Others are high-profile governors or members of Congress. Yet many are also little known to the general public -- and may remain so. Obama has less than 11 weeks to staff his new administration. Some names often mentioned as possible appointees to top posts: DEFENSE SECRETARY Defense Secretary Robert Gates. Former Navy Secretary Richard Danzig. Sen. Chuck Hagel, R-Neb., critic of Iraq war, retiring from Senate. Sen. Jack Reed, D-R.I., member of Senate Armed Services Committee.
