Thanks to mumpish for pointing out that five departures is not an unusual number after all. He shared the link to this article about the Clinton cabinet departures, and I had forgotten about that, honestly. (Also, work blocks so much stuff that I hardly even bother searching any more, to be honest -- it's not that I'm too lazy, it's that there is so little I can access outside of CNN, LJ, and the NY Times. Had I been at home, I would have done some fact checking.)
Anyway, thanks for setting me to rights on that.
However, his information doesn't come without a price. His post about "It's not unusual" has forced the Tom Jones tune into my head, and I can't get rid of it. *cries* Help! :)
