(CNN) - Mitt Romney's latest television ad emphasizes his commitment to his faith and family – but includes a blunder he made at a debate when lauding his decades-long marriage.
The 30-second spot, which the Romney campaign said would run in Iowa and New Hampshire, is called "Leader," and utilizes Romney's answer to a question at a debate in early November.
"I've been married to the same woman for 25 – excuse me, I'll get in trouble – for 42 years," Romney says in the ad. "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."
The ad intersperses home video footage from Romney's family, showing the former Massachusetts governor and two-time presidential candidate playing with his children when they were young, and his wife Ann from the early days of their marriage. The ad also uses images from Romney's time as head of the 2002 Salt Lake City Winter Olympics.
Romney's focus on marriage comes as former House Speaker Newt Gingrich, who has been married three times, is rising rapidly in national polls, as well as surveys in key early voting states.
Gingrich has been married to his current wife Callista since 2000.
Romney has previously bought ad space in New Hampshire and Iowa, including a commercial slamming President Barack Obama on the economy, and a spot touting his experience in the private sector.
