Professor Bainbridge has a long post on the subject proving something everybody already knew or certainly could have guessed: he knows a lot more about this stuff than yours truly.

Anyway, for the lefty emailers bombarding me about the subject, I return to my basic position: I have no idea what happened and I think the appearance of impropriety certainly meets the threshhold for an investigation. But I see no reason to get obsessed with it, or even powerfully interested in it, until we know a lot more. And, if it costs Frist his presidential bid, I won’t lose sleep.
