Mark Kleiman calls it like it is:

Democrats should stop getting the vapors every time a Republican accuses them of being "soft on terror," and stop whining about how mean and divisive the Republicans are being (though indeed Bush's preference for political point-scoring over national unity is indeed one example of his unseriousness about fighting the GWOT). Instead, they should point out in detail how the total fecklessness of the Bush Administration has made the country less safe.
