As Justin Raimondo makes clear, the Scooter Libby trial is really a trial of Dick Cheney, for his manipulation of prewar intelligence to gin up the case for invasion of Iraq. As a result, it's possible we may finally learn how the "uranium from Africa" language found its way into Bush's prewar speech, even after it had been deleted, at CIA's instance, from a previous Bush speech. That revelation--and it's certain the source of the language was Cheney--could well lead to a broader Congressional investigation of "who lied us to war?" And that investigation could lay the blame directly on Dick Cheney and his neocon minions.
It's long been obvious that most Democrats in Congress do not want to "waste political capital" on impeach-Bush hearings given the small amount of time remaining in his term, for one thing. But large segments of the voting public might, upon learning of Cheney's role in prewar lies, want the latter's pound of flesh--anything to settle their stomachs. This might well lead to Cheney's resignation "for health reasons" and the installation of a new Veep in the months before Bush's term is over, a likelihood because (1) it might give that new office-holder a leg up on a run for the White House in 2008; and (2) because installation of a new Vice President would remove the prospect of a President Pelosi, should anything happen to Bush.
How likely is all of this? Stay tuned. To quote Betty Davis, "Fasten your seatbelts. It's going to be a bumpy night."
