After Greenspan:

Speaking of Greenspan, one of the hottest guessing games in Washington these days is over who will succeed him when he ends his tenure in January. Bush-watchers insist the President will name someone who has served in his administration and shares Greenspan’s hold-interest-rates down philosophy. The most oft-heard names are those of Ben Bernanke and Glenn Hubbard, who have been Bush economic advisers, and Peter Fisher, a former deputy undersecretary of the Treasury for domestic finance.
