Fine old families of Texas

Brad DeLong marvels:

At one time I thought that Mark McClellan would be one of the very few who would manage to get out of the Bush administration with his reputation. It's looking like I was wrong.

Why would anyone think this about any of the McClellans? My husband went to school with them, and the whole family has always been a piratical band of opportunists. Humorous anecdote: Evidently, young Scott McClellan used to harass the sister of one of my husband's friends, until she got tired of it and beat him up.
