Just some thoughts.
Secretary of State:
Richard Holbrooke, former UN Ambassador
Secretart of Defense:
Wesley Clark, retired four-star general
National Security Advisor or Director of Homeland Security:
John McCain, Senator from Arizona
Attorney General, FBI Director, CIA Director, Energy, Treasury, Commerce:
no picks at this time
I'd suggest
Colin Powell keep his job as Secretary of State if he hadn't already said he'd be retiring next year no matter the outcome of the election.
I don't know enough about the qualifications for Attorney General, so I can only hope whoever gets it makes it his/her first task to remove the
Ashcroft curtains.
