Tuesday, Jan. 29, 2008 | Re: Union-Tribune Diminishment: On the plus-side, editorial page dragon Robert Caldwell announced Sunday that he is leaving. My question is, how soon? And can we expect that GOP stalwart and editorial page editor Bob Kittle will be trailing after? (We can only hope.) On the down-side, theater critic Ann-Marie Welch and film critic David Elliott are both out the door, and they were two reasons I buy the paper. Doesn’t anybody want to buy this property and breathe new life into it?
