Chait picks up on one:
Notice that neither Romney nor Krauthammer quite say that the growth-boosting effects of the deal are a reason to oppose it. Rather they argue that the higher growth isn't worth the budgetary cost, making it surely the first time either one of them has rejected a [debt]-financed tax cut on the basis of its effects on the national debt. It will be interesting to watch anti-deal Republicans try to make their case by hinting at electoral ramifications without coming out and saying so directly.
