No comment on the Libby Clemency/potential-pardon other than this: Corrupt Republicans tend to be corrupt out of principle. Corrupt Democrats tend to be corrupt out of greed.
(Which is more dangerous for our Republic?)
Most Republicans who get into trouble did their deeds, like Libby, out of dedication to the Party, the Administration, or some other higher ideal. Most Democrats who get into trouble, like Representative William Jefferson, are looking to cash in.
If Republican officials tend to be men of principles, and Democratic office-holders are men of cash, then who are the men of law?
