The way I saw it last night was on CNN's streaming of the Romney party on the big screens at either side of the stage. No audio and small and a bit blurry, so it was hard to tell what was going on. I said to Mr. beac "Is that Ann Romney being called in to stabilize Mitt before his speech?"
A few minutes later I read on DU about Megyn's spontaneous-rehearsed Karl-haz-a-sad "confrontation" of their numbers guys. Hilarious that they moved them down a long hallway just so Meggie could do a dramatic reality-TV hall walk if needed!
