It’s Washington’s favorite parlor game during a presidential transition: trying to figure out who’ll land a top spot in the new administration. President-elect Barack Obama is weighing an array of Washington insiders and outsiders, including some Republicans, for Cabinet and other top positions, according to Democratic officials.

Just like the stock market, names rise and fall weekly, some zooming to the top, others dropping out of contention. Hillary Rodham Clinton suddenly is considered the top prospect for secretary of state, although other names remain in the mix. It looks like Eric Holder, former deputy attorney general, is on track for attorney general.

Some of those who are the subject of speculation already have been chosen by Obama to serve as part of his transition team. For example, former Sen. Tom Dashcle was picked Wednesday to lead Obama’s working group on health care, the same day word surfaced that he’s accepted Obama’s offer to serve as secretary of health and human services.

Some names being floated are surprising, such as former Bush Secretary of State Colin Powell for education secretary. Others are high-profile governors or members of Congress. Many are also little known to the general public — and may remain so.
