I approached John McCain's outspoken mother, Roberta, in a hallway (you remember she'd once said Republicans will have to "hold their noses" and vote for her son). She was gracious and lovely and, as I introduced myself, her handlers came and dragged her away. "They won't let me talk," she said, helplessly, seemingly pleading with me for help. "They won't let me do interviews." I have it all on tape.
