It makes perfect sense for George Bush to commute the sentence of Scooter Libby.
There really isn't anything Bush could do to diminish his reputation even further, so why not do something to shore up the hard core conservative base of the Republican Party? What's the downside: Democrats and moderates will lose respect for Bush? They already have no respect for him.
Bush could pose nude with Ann Coulter and a penguin and the conservative base would praise him for it. On the other hand he could personally behead Osama Bin Laden and the Democrats would find fault.
