From Susan Estrich's latest column:

It's too bad, in a way, that John Kerry was able to win the Democratic nomination so easily last time, without any of his competitors in fact taking him on about his war record and then his post-war criticisms of American troops. It might have caused him to think twice before beginning his acceptance speech at the Democratic convention with the ill-fated line, "Lieutenant John Kerry, reporting for duty." Indeed.

You see, this hurts Clinton more than it hurts Obama--she's only doing it because she cares.
