What's good so far: called out "lies" in the debate. Reminding everybody that the Bush tax cuts and wars created huge deficits.
Not so good: weak defense of public option. Did a good job of defining it as the center by calling single payer the "left," but by arguing that it wouldn't really do that much, "Let me be clear, only an option for those who do not have insurance, less than 5% of Americans will sign up," isn't much of a strong defense of the public option.
Update: Will invoking Kennedy help bring Hatch around? Or McCain? Or Grassley? That'd be nice, but it's not too likely. Nonetheless, good on him for recognizing Kennedy.
