Fedblog says that candidate Rudolph W. Giuliani was talking recently about the wave of retirements about to hit the federal workforce. About 42% of federal civilians will retire during the next two presidential terms. Giuliani's response: "Some politicians assume that we'll just replace all of them," he said. "I bet there are some politicians in the other party -- I don't know, maybe in ours -- that think we ought to increase them. . . . Here's what I would do: I would seek to replace only half of them."
