Seems that Judge Kavanaugh was a DKE as an undergrad. DKE was notoriously the most most drunken (well, maybe tied with a singing group) and least evolved student organization when I was an undergrad at Yale, only a few years before Kavanaugh. It is not a good recommendation for a Judge, much less a Justice. Certainly not disqualifying on its own, but it helps set a context for other things.
Someone kindly sent me a link to an old Yale Daily News article about what DKE was up to the year Kavanaugh was a sophomore, which includes the photo above. Kavanaugh was already a member by then. Nothing to be proud of, although one should be careful to note this is guilt by association; he’s not in the photo. But those guys hung together.
