I hardly even know what to add to this. In a well-framed, critical yet optimistic, to the point, and refreshingly presidential speech in Iowa on Friday afternoon, Mitt Romney simply and clearly laid out his economic vision for his presidency. He touched on all the major domestic spheres of our economy and our society — our budget, education, energy, health care, regulations, you name it — without shying away or making excuses. It was a remarkable difference from the petty tone and shrinking subject matter we’ve heard from President Obama of late, and as Romney points out, the president so often likes to blame his predecessor for the problems he “inherited” — but Obama also “inherited” the greatest, most productive country on the planet, and just look at what he’s done with it.
