WASHINGTON - Mitt Romney's Presidential campaign has produced a new TV ad, called "Leader", that will be running in Iowa and New Hampshire by the end of the week, Fox News has learned.

The ad uses Romney's remarks during last month's CNBC Michigan debate which were considered by media critics as one of his best debate performances of the primary cycle. In them, Romney makes his case that the consistency in his life is actually one of his strongest assets of his candidacy.

"I think people understand that I'm a man of steadiness and constancy," Romney begins."I don't think you're going to find somebody who has more of those attributes than I do."

The ad then uses a montage of images of Romney with his telegenic family over several decades.

"I've been married to the same woman for 25 - excuse me, I'll get in trouble - for 42 years." Romney says in a moment that received approving chuckles from the debate audience that night.

"I've been in the same church my entire life. I worked at one company, Bain, for 25 years. And I left that to go off and help save the Olympic Games," Romney says, describing enduring periods of both his church life and business career.

"If I'm President of the United States, I will be true to my family, to my faith, and to our country, and I will never apologize for the United States of America, " The ad ends decisively.
