For a while, it was a minor piece of conventional wisdom that Bush had to choose whether to attack John Kerry as a flip-flopper or as a liberal. This never made sense to me, since it’s perfectly possible to be a flip-flopping liberal. In today’s New York Post, Dick Morris points out that the two charges could actually be complementary. Bush attacks Kerry as a flip-flopper now, then attacks him as a liberal later, and when Kerry denies that he is a liberal, Bush gets to say, “There you go again with the flip-flopping.”
