David Brooks tries to make the case against Gingrich and winds up moderating him in many ways. Moreover, he raises salient issues in the contest between him and Romney: Gingrich probably does see a continuity between himself, TR, and Hamilton. But is there a constitutionalist in the house? If not, is a right-wing Progressive better than a competent manager? Which would bring us back to founding principles?
TR rejected natural rights in favor of a new, collective nationalism, while Hamilton was clear in basing the emerging new republic on natural rights. I haven't seen this concern in Gingrich but rather more a kind of Newt nationalism. How that bears on the Declaration and the Constitution is the issue conservatives face.
E.J. Dionne plays his role exquisitely, showing the link between TR and Obama, though he gets FDR wrong in the process: FDR had laid out his revolutionary strategy in his 1932 campaign, in his speech on Progressive Liberalism.
