I'm a liberal, by and large, and don't really care if Bush pardons Libby or commutes his sentence. Its his right and politics motivate a lot of these things in every administration. In that sense, whatever.
I do think it is another example of this administration acting in secrecy and gamesmanship and thinking itself and its minions above the law and, more importantly, common sense of decency and fair play. Cheney over the last few years has proven that the only thing greater than his willingness to engage in some pretty hard hitting and below the belt tactics is his arrogance in refusing to be held accountable.
He's just so convinced that he's right about everything that he will simply beat the living crap out of anyone that dares to disagree and shed light on the contempt with which Cheney holds everyone but the true believers in his own camp.
He's simply an arrogant (fill in your favorite curse word describer).
