I've now heard back from the government chair, Valerie Bunce, and Prof. Isaac Kramnick, so in fairness I want to note that here. Prof. Bunce did not want to comment, except to say, "As I told Jeremy, I am very sad that he is leaving. I followed the same procedures in Jeremy's case that I have followed in all cases where there is an outside offer in the making." Kramnick said in an e-mail: "I heard about Jeremy leaving from his resignation e-mail to his colleagues, which was the first inkling I had of the possibility he might leave. I am saddened at his leaving the department because I always felt that, like myself, he always put undergraduate teaching at the top of his priorities." I should also note that Kramnick has been on leave, and it's still spring break, which might account for the relative lack of response from the department.
