It was a good speech. Not a soaring or flowery speech, but then it wasn't intended to be. Obama has shown one of the most important characteristics for a successful candidate: flexibility. Realizing that he hasn't polled well with working-class whites whose primary concern is the economy, he re-tooled his message to focus on precisely those issues. Having a number of working-class white delegates warm-up the crowd was a great touch. Barney Smith for Secretary of Labor! Obama systematically hit every single one of the criticisms that the Republicans have levelled at him--that he's elitist, that he's a celebrity, that he's not "one of us." He hit McCain, though it could be argued not hard enough, while careful to pay tribute to his war hero status, a courtesy certainly not afforded John Kerry by the GOP in 2004. Overall, I was impressed, as I have continued to be impressed (and surprised) by Obama since he first entered the race. I feel much better about November 4 than I did just a few days ago.
