[Obama] is less concerned about trying to tear down his opponent and more concerned about laying out and having a real conversation about the issues that people are facing on the ground.
Let's look at tonight's speech.
By my count, Obama starts ripping into "Bush/McCain" with this paragraph of his speech:
Tonight, more Americans are out of work and more are working harder for less. More of you have lost your homes and even more are watching your home values plummet. More of you have cars you can't afford to drive, credit card bills you can't afford to pay, and tuition that's beyond your reach.
These challenges are not all of government's making. But the failure to respond is a direct result of a broken politics in Washington and the failed policies of George W. Bush.
And, Obama concludes the "attack" portion of his speech at this point:
So I've got news for you, John McCain. We all put our country first.
Obama's entire speech was 4,695 words long. That attack section was 3,189 of those words. That's more than two thirds of the speech "trying to tear down his opponent."
Perhaps the commentary on his speech I'm finding most resonance with is from Mark Hemingway: "There's a fine line between indignant and angry, and Obama is swerving back and forth all over it."
Update: Compare. Contrast.
