Dictated on board Air Force One en route from New Hampshire to Florida: Dear Diary, Let me be perfectly clear: I am a firm believer in being a moving target at uh... critical times like this. With the Big Day only a couple days away I am criss-crossing the country campaigning at dizzying speed. Today it's DC to New Hampshire, south to Florida, north to Ohio, then uh...southwest to uh...Colorado. All this while hoping fervently that the old coot Biden keeps it together for just a couple more days.
