It doesn't look like President Obama will borrow a page from President Bush's post-midterm playbook.

Senior administration officials have not been briefed on any plans for the President to announce a staff shake-up at his 1 pm news conference today. They said they do not expect him to make any immediate announcements for symbolic effect or to satisfy the needs of the news cycle.

A dramatic announcement "is not his style," said a close adviser.

The officials do expect some staff turnover before the end of the year. "But there won't be any huge surprises," the adviser said. "A lot of these decisions are being made with everyone in the room." Aides cautioned that they were not aware if any officials had offered to resign, and they assume that would be done in private.

The aides did not want to be named because they did not want to be seen as stepping on the President's message this afternoon.

There's a sense in the White House that significant staff shake-ups would justify the critique that the White House is responsible for the economic situation.

New Chief of Staff Pete Rouse is leading a review of possible staff moves. Already, there have been major changes made on the national security front, with National Security Adviser James Jones replaced by his deputy,Tom Donilon.
