This charge in the Bush ads is kind of made up, but seems to be playing amazingly well. It is hitting Kerry at a maximum point of vulnerability, when he has promised all sorts of spending during the Democratic primaries, but hasn’t yet recalibrated or fully fleshed out his fiscal plans. The ad implicitly asks the question: Kerry has a $900 billion health care plan so how is he going to pay for it? At the moment, the answer seems clear: with more tax increases than he’s willing to own up to. If Kerry eventually comes up with a different answer, it will seem as though he did it under pressure and as a matter of political expedience, thus reinforcing an aspect of the flip-flop line of attack against him.
