I know the arguments. I know the stalling. I know people have heard it before. I don't care: impeachment proceedings should begin immediately. Not later. Now.
It doesn't matter if it's late in his term. It doesn't matter if Republicans and Blue Dogs will try to stall. It doesn't matter if there aren't enough votes to impeach. What matters is that Congress remembers its duty to perform oversight and actively investigate the criminal acts of this administration. That is all that matters.
As a bonus, once the facts are revealed and displayed for the public in such a way that the media can't ignore it, voting against impeachment will become political suicide. No one but the most corrupt or self-deluded can possibly assert Bush's innocence even now, when only a fraction of the details are known.
The President is not above the law, no matter what Cheney wants to say. Else we can no longer claim to be a nation of laws.
