Kerry explained to supporters recently that hed voted for the $87 billion before hed voted against it. In his mind, evidently, he was merely explaining (with a mordant sense of humor) how the Senate works. But now that line is the centerpiece of a BC04 attack ad. Kerry told financial supporters in New York the other week that his objective, for now, was to preserve my acceptability. Thats a pretty low standard but one he wont meet if that is his only goal. So far, his strategy has amounted mostly to: Vote for me, Im not Bush. Thats not enough, especially if Kerry is seen by most voters the way the BC04 ad portrays him: as a flip-flopping manipulative insider.
