Probably quite a few volunteers did just that, also at personal sacrifice. They, however, don't have columns in the Wall Street Journal n which they could announce it.

See? "There you go again." :) Noonan had a responsibility to inform her readers that she was leaving the WSJ and why - to avoid any conflict of interest. But you seem to twist that into self-promotion or selfishness.
Also - there are quite a few Bush supporters other than Noonan at the WSJ. Any of them take leave w/o pay? How about our pals at the Wash Times?
