Are a dry run on impeachment. Bush is warned on what the Dems will do if he crosses certain lines before the end of his term. Make no mistake: this "crisis" or "showdown" is nothing, the signal is everything. This is pre-emptive, asymmetrical political warfare. Given the international stakes, I approve--for the sake of this country and the world. Overreaction? Not with this administration's record. And no, please don't offer analysis of this process WRT to either Clinton's impeachment or his previous treatment of U.S. attorneys. Those data points have little to do with this effort at political deterrence. Signal-to-noise hard to fathom for some, easier for others.
