Bush commutes Libby's prison sentence

I sure did not see that one coming....NOT. I know that commute'ing a sentence is the right of a president, and its sure hell of a lot better then a full on pardon.

I think any faith that I might have had in his leadership is now just gone. We only got, what, 2 more years of him in office? Can we impeach him now or does it really have to be later?
