A senior Obama adviser has suggested Defense Secretary Robert Gates might be a holdover from the Bush administration if Democrats win the White House. The adviser, former Navy Secretary Richard Danzig, said Gates could do “even better” under an Obama presidency. Danzig went on to say Obama has agreed with many of Gates’s policies as head of the Pentagon. Gates joined the Bush administration in December 2006 and has firmly opposed any timetable for the withdrawal of US troops from Iraq.
