The Democratic convention just played a tribute to Sen. Teddy Kennedy, and then he walked out on stage to speak, despite his cancer. He was introduced by Caroline Kennedy as "Uncle Teddy," and spoke eloquently and movingly. Maria Shriver wiped away a tear. A moving moment.
Update: Watching Michelle's brother speak (sorry, didn't catch his name) was enlightening. He was a bit nervous, especially at the start. Who wouldn't be? I think he did a nice job introducing Michelle.
