Discredited experts

A guess at what David Brooks means when he says this (via Matt):

There simply aren’t enough Republican experts left to staff an administration, so he will have to throw together a hodgepodge with independents and Democrats.

I'm guessing he's saying that a lot of the Republican experts have the taint of Bush on them. McCain can't hire Wolfowitz, Feith, Andy Card, etc., etc. because they are too closely tied to an incredibly unpopular president. Or, like Jack Goldsmith, they've written tell-alls and are now persona non grata to the Republican party.
