My immediate impressions of Barack Obama's speech is that more than anything, it was a tactical treatise.
He tried to pre-empt Republican attacks to come and gave a few more specifics to satisfy those who say he is an empty suit. It was the same old liberal ideas we've heard for four decades, but of course delivered in a superior way than previous liberal presidential candidates.
There wasn't a single new idea or theme. He probably believes he doesn't need oneâ€”he'll ride the dissatisfaction with Republicans to victory.
In a way, a very defensive speech. John McCain needs to jump right back into his face. If he does, he will win.
