I'm very aware of both but it could cause political hell to pay for the Democrats if they tried either one, particularly now that the whole Plamegate thing has been exposed as an enormous lie.
So they pay a bit in 2008 - meantime, we would have gone through 2 years of impeachment, and much worse, we would have turned Iraq over to terrorists. Not to mention confirmed for the world that the US can't be trusted.
There's no snit worth that, IMO.
