"Well, of course … It's true," she said. "But it's not just the campaign's fault. I believe it was the media's fault as well. He was not being given a fair shake. People weren't allowed to really see him for who he was."

Mitt Romney was criticized during the campaign for not showing more emotion — a quality his wife said is not representative of his personality.

"I'm like a she-lion when it comes to defending Mitt," Ann Romney told Fox. "He's an exceptional, wonderful person."

She also conceded that the GOP campaign was "blind-sided" by the enthusiasm for President Obama.

"I think they had a better ground game," Ann Romney said of Obama's campaign. "We certainly had the passion coming from our side, and I don't think we were as aware of the passion that was coming from the other side."
