One issue I would give more emphasis to: Kesler rightly wants conservatives and Republicans to outflank Obama by returning to the principles of the American Founding, instead of being distracted by this or that tactic or even worse by misunderstanding Reagan conservatism. But even here Obama can readily block the right by his own appeal to the Declaration of Independence, as he does in his books. And Republicans play along with this--Kesler does not note how often Bush appealed to the Declaration--by failing to make the Declaration a document affirming limited government, a denial to the death that government is based on arbitrary will.
Both the left and the right make the Declaration a justification for active government. That is one reason liberals like it and conservatives hate it. (Robert Bork's misguided cynicism about the Declaration was on to something.) Kesler is of course right about returning to the founding, but we're in the fight of our lives against a post-modern post-nationalist who has embraced the Declaration for the wrong reasons and will twist it to his convenience. Speak of the triumph of the will! The argument is that basic, about who we are as Americans. And, despite the Obamacare setback, he is still the Tiger Woods of the course.
