He writes in his June Diary:

In mid-June I posted a brief remark about Bobby Jindal’s having participated in an exorcism. Over the next few days I learned a thing that left me, I must say, somewhat depressed: I learned that quite a lot of NRO readers believe in demonic possession.

I plead guilty. While defending Derb’s right not to believe as I do, I wrote last month:

the insinuation appears to be that Jindal is a weirdo. The article that is now circulating revolves around an “exorcism” Jindal experienced as an undergraduate at Brown University. While exorcisms should not be tried at home or in your dorm room, it is not breaking news that there is evil in the world. That a young man recognized this while in college is not a scandal.
….
In his New Oxford Review piece on encountering the demonic in college, Jindal concluded, “I learned a lasting lesson in humility and the limits of human understanding. Was the purpose of that night served when so many individuals were inducted into the Church? Did I witness spiritual warfare? I do not have the answers, but I do believe in the reality of spirits, angels, and other related phenomena that I can neither touch nor see.” While we’re all likely to hear more details about what Jindal described in his “exorcism” piece, most stories will skip over the bottom line. Jindal knows there is good and evil in the world, and prays for the wisdom to know which is which and to stay away from the evil. That’s a confidence-inspiring moral compass. The essay in question demonstrates an impressive core to Jindal. If only more politicians had such humility — and Jindal had it before he was 25! As George Washington put it, “No people can be bound to acknowledge and adore the invisible hand which conducts the affairs of men more than the people of the United States.” Bring on the public servants who so believe and their defense of the right of others not to.
