Remember, he’s the “adult in the room.”

Washington (CNN) — Mitt Romney rejected the notion that he’s shifted his positions on health care Thursday, telling CNN’s Wolf Blitzer that his record shows consistent evidence of conservative platforms and beliefs.

Blitzer pushed Romney on why he had changed a passage in his book “No Apologies” that referred to a health care plan enacted in Massachusetts when Romney was governor. In the hardcover version, Romney wrote, “We can accomplish the same thing for everyone in the country, and it can be done without letting the government take over health care.”

When the book was published in paperback, the line read only, “It was done without government taking over health care,” without mention of the plan’s cross-country prospects.

Romney defended the change, saying it was simply a clarification of established viewpoints. . .

Romney used the interview Thursday to put some distance between himself and Texas Gov. Rick Perry when asked if he would use the word “socialist” to describe the Obama White House.

“Well, you know, words have a lot of unintended meanings and calling people socialists probably goes on the fact that it is true that President Obama’s team and the president himself seem to believe that government has a better approach to our economy than the private sector, and I disagree with that approach,” Romney said.

Romney continued, “I don’t use the word socialist, or I haven’t so far, but I do agree the president’s approach is government heavy, government intensive and not working.”
