Please understand that Knippenberg himself has no say in the selection either (and additionally feels that "Harvard as a whole is probably ungovernable"). He just didn't like that another website had asked for suggestions and there wasn't a conservative on their list, so he's just trying to open things up a little.
He gets the ball rolling with some suggestions of his own. For instance, Zell Miller. The reason he gives for this candidate?
Zell Miller knows a good bit about living in an institution with people who can’t stand him.
For another example:
Bill Kristol is a Harvard man; unfortunately, his experience in the White House probably doesn’t adequately prepare him for the Machiavellian nastiness of faculty politics.
I'm not sure I'll play, but I know a couple of you who are pretty good at this variety of zinger. Have fun. Please play nice, but have fun.
Update: James D. Miller is campaigning for the post over at TCS (aka Tech Central Station). See Hey, Harvard, Hire Me!
