How can those Republicans keep a straight face?

I watched Kay Bailey Hutchinson (Republican Senator from Texas) present the Talking Points to Tim Russert (Meet the Press) on Sunday morning -- since Fitzgerald can't find a real crime to accuse Rove and company of, he's fallling back on perjury, how lame is that? It was positively surreal. The Republicans had a somewhat different attitude about perjury when Bill Clinton lied about his sex life. They were damn near apoplectic about it. How can these people keep a straight face when they deliver these absurb comments, which they surely recognize for the pablum it is.
