Romney and Gingrich battle for the hearts of budget hawks.
UPDATE: Earlier today, Romney spoke about Ryan on the trail in New Hampshire:
“Speaker Gingrich said that [the] Ryan plan was right-wing social engineering,” Romney said. “I was astonished. I said it was a courageous step that I supported… Speaker Gingrich was exactly wrong on that. He might hit the ground running but not in the same direction I’m going to go.”
