State of the Union & Nancy Pelosi

Bush is speaking about terrorism and Speaker Pelosi looks, shall I say, a little uncomfortable. If she was speaking I would assume that she was lying; or does she always look like she is lying? When somebody blinks as often as the Speaker of the House currently is I simply assume that the person speaking is not on the level. Maybe "shifty" is a better description.

Update: It looks like Charles Johnson over at Little Green Footballs also noticed the feverish blinking.
