The degree to which Congress was or was not weak-willed is again, a political judgment within a democratic institution -- NOT fascistic.
Uh, "failure to comply" (the point) is not a political judgment, it is a fact. Let's try to stay on point.
What was unprecedented about Libby? I am not certain you understand the word, "precedent".
Commuting a sentence before one day of that sentence had been served is unprecedented, and almost certainly beyond the bounds of the law. That is not the same as a more traditional pardon. Find a precedent for that, and I'll gladly concede your point. In regard to the wiretaps, it is no great leap to equate a cry of "retroactive immunity" with an admission of guilt.
Then we have unprecedented numbers of signing statements ('the law applies to everyone but me'), Cheney's declaration that his office is not part of the executive branch, other Bush administration officials ignoring
Congressional subpoenas, the list of actions that you find entirely reasonable and Democratic goes on and on and on. I only hope that our Attorney General in 2009 pursues these criminals with appropriate zeal.
Your other arguments simply demonstrate how our form of government has reined in the fascist bent of the administration, reinforcing a point that had already been made.
