Ann Romney, the wife of Republican presidential candidate Mitt Romney, told a Nevada television station her main concern if her husband wins the upcoming election would be over his state of mind.

"I think my biggest concern, obviously, would just be for his mental well-being," she told KTVN-TV Thursday. "I have all the confidence in the world in his ability, in his decisiveness and his leadership skills, in his understanding of the economy, in his understanding of what's missing right now in the economy - you know, pieces that are missing to get this jump-started. So for me I think it would just be the emotional part of it."

Romney was in Reno Thursday campaigning on behalf of her husband, the former governor of Massachusetts, and addressing accusations that he has dismissed middle-class Americans.

"Mitt is a person who cares," she said. "That's why we are running, because we care ... he does not fail. As president of the United States, he will not fail."

She also told the stations all Americans should be concerned about the prospect of Obama being re-elected.

"This economy has been under his control for the last four years, and we have seen no jobs," Romney said. "It's been a jobless recovery."

Revised data by the U.S. Labor Department released Thursday suggests that 125,000 additional non-farm payroll jobs have been created since Obama took office in January 2009.

Romney's interview with KTVN begins around the 6:30 mark of the station's report, aired Thursday evening, and can be seen below.
