The point would be to say, first, that this is how seriously we regard Bush’s offenses: that we regard the gap between what the Administration told us, and what they knew, in the run-up to war, to be impeachable. We regard Bush’s willingness to spy on Americans without statutory authority, and without oversight, by claim of essentially unlimited wartime C-in-C powers, as impeachable. We regard the creation of a secret overseas prison system, hand in hand with the all-too-frequent use of what we once called torture, as impeachable.
There comes a time to say these things are serious shit, whether or not we can do anything about them. For years before they took control of Congress, the GOP took stands on a whole bunch of stuff they were going to lose at. That’s what you do if you’ve got any guts.
Because, second, if you’re out of power now, and you want to get back in, you’ve got to let people know what matters to you, what your values are.
Part of those values is that there are lines that shouldn’t be crossed. Impeachment resolutions make it clear that you believe those lines have been crossed, and it’s time to do something about them.
