MSNBC host Lawrence O'Donnell gets in, what may be the Last Word, on the biggest loon ever elected to Congress. I don't agree with O'Donnell on anything really, but there is a reason he is giving Fox's Greta Van Sustern a run for her money in ratings. O'Donnell knows what makes great television; I guess his years working on The West Wing continue to pay off for him. The Other McCain has the video so I won't post it here. Watch Ezra Klein's facial expression (about the 2:35 mark) as Grayson is really on a tear. Klein's expression was priceless.
