It would be just for the President to pardon Lewis Libby, but it would set a very damaging precedent.
There are excellent reasons for a pardon – Libby leaked nothing that had not been published, the Plame woman was not covert, the prosecutor is a crook and the judge sentenced Libby using evidence never presented to or tested in his court. Libby’s correct response is to appeal.
And if the worst happens and he gets 2 years in jail, so what? Everybody knows this is a political hit, so his reputation will be undamaged, and he can easily get back the money he loses by a book deal.
Whereas if the president pardons him, that sets a precedent for an amnesty for 12 to 20 million illegal immigrants, and that could be the end of the US.
And if the president doesn’t pardon Libby, it’ll be impossible for him to continue arguing for an amnesty for these serial felons.
Libby strikes me as a brave and decent man, so he’ll probably go along with this analysis and take his lumps.
And 2 years in the slammer gives him ample time to figure out how to deal with his persecutors.
