The Wall Street Journal reported on Tuesday that a Newt Gingrich newsletter from April 2006, the month that Mitt Romney signed the Massachusetts health care bill into law, praised Romneycare. “The most exciting development of the past few weeks is what has been happening up in Massachusetts,” read the “Newt Note” from 2006. “The health bill that Governor Romney signed into law this month has tremendous potential to effect major change in the American health system.”

Asked about the newsletter in an interview with CNN Tuesday, Gingrich said he didn’t fully grasp the problems with the law at the time, but he has learned from his mistake, while Romney has not.
