Missed the point by a mile.
Democrats simply stop talking about scandals and other issues like election problems when they were no longer politically useful. That should clue you in on the basis for their "morality."
They don't give a rat's ass about the "culture of corruption" and never really did, except to win an election. You'd think their current habit of following cheerfully in Abramoff's lobbying footsteps would clue you in.
DeLay's trumped-up indictments are being thrown out in the courts, and most of the other Great Scandals are simply fading away.
