"Federal Reserve Chairman Alan Greenspan's term doesn't expire for another six months, but that hasn't stopped presidential candidates from offering President Clinton advice on reappointing him to a fourth four-year term as head of the central bank.</br></br>Their comments have ranged from replacing Greenspan because he's doing a lousy job (Steve Forbes) and thinking others could do just as well (Bill Bradley), to enthusiastic endorsement for his ""outstanding A-plus-plus performance"" (Al Gore) and extremely enthusiastic endorsement (John McCain).</br></br>During a Republican debate earlier this month, the Arizona senator said, ""If Mr. Greenspan should happen to die--God forbid--I would do like they did in the movie 'Weekend at Bernie's.' "" Referring to a comedy in which two men take over a dead man's beach house, he said: ""I'd prop him up and put a pair of dark glasses on him and keep him as long as I could.""</br></br>And President Clinton? When asked about Greenspan's future at a news conference in July, he said: ""I have, as you know, enjoyed a very good relationship, both personally and professionally, with Mr. Greenspan. I think he has done a terrific job. I have no idea whether he would even be willing to serve another term.""</br></br>He added that he expected to decide in a ""timely fashion."" That, it turns out, is just what he is doing."
