“In a statement, the Bush campaign called the [new Kerry] commercial `a futile attempt to obscure the fact that John Kerry’s new spending proposals would result in a tax hike for all Americans.’” OK, I can buy that it’s a reasonable inference that Kerry’s $900 billion health-care plan would mean a $900 billion tax increase, if he says he won’t add to the deficit. But how do we know it would be a tax increase on “all Americans” as oppossed to “the rich” (a category that will, of course, be pretty broadly defined).
