This is one of those well-written pieces that fall under "required reading" (excerpt):

"....Congress passes laws forbidding torture; Bush and Cheney ignore them. Congress issues subpoenas and demands documents for its corruption probes; Bush and Cheney ignore them. Bush's "signing statements" explicitly state that he will follow only those parts of the law that suit him. Congress could vote tomorrow that Iran cannot be attacked without a formal declaration of war, and Bush would attack whenever he chooses anyway, calling it an extension of the congressionally authorized action in Iraq, a "defensive" action to protect the troops. Congress can pass any law it wants, but if you have an executive branch that considers itself above the law -- as this one demonstrably does -- then it doesn't matter. As long as Bush and Cheney remain in power, their criminal enterprise will go on. "Thus impeachment is not a "distraction" from efforts to end the war in Iraq, or stop a new war with Iran, or quell the vast and sickening corruption of the regime. It is their prerequisite. And even if impeachment is "politically impossible in the present circumstances," as Bush enablers like the pusillanimous Nancy Pelosi likes to tell us, it should be shoved to the forefront of national debate nonetheless. Let us have a "constitutional crisis;" let us bring our festering sickness to a boil. Let's lay it all out, and let people declare once and for all where they stand. Are you for the republic, or do you hold with tyranny, torture and mass murder? Let's draw the line at last, and be done with all pretense...."
