I really liked the speech. Optimistic. Jolly. Pointed. Unpompous. Sunnily inclusive. Full of personality and a real pleasure to listen to. Everything his former compatriots, including The One, are completely incapable of.
The overall message, something along the lines of "Come on folks, let's see what good things might happen if we all stop being a-holes," contrasted favorably with The Anointed's edgy, us-against-them, payback--time-is-coming, convention speech.
One thing is obvious. Joe Lieberman did not leave the Democrats. The Democrats left him.
