OKAY, THIS IS NEW: So I was in my office grading student papers when a congressional candidate dropped by. No, really: It was Van Irion, who’s running in the Republican primary in Tennessee’s 3d district (for the seat being vacated by Zach Wamp, who’s running for Governor). He seemed quite Tea Party-friendly in his views. I’ve never had a candidate drop by my office before, so — following my own advice to have a digital camera handy at all times — I took a picture.
