Mitt Romney revealed today during his first interview since he lost US presidency that he believed in his heart he was going to win the election and go on to the White House, and that “it kills me” not to be president.

Former GOP candidate Mitt Romney, 65, said today in his first interview since losing the election that while he believed he was going to become commander-in-chief, early polling numbers spelled out trouble, and he began to have a “slow recognition” that Barack Obama would win once seeing that Florida was a close race.

In the interview with Fox News Sunday, Ann Romney, 64, also confirmed during the show that she was approached by ABC’s Dancing with the Stars, but turned it down, saying: “I would have loved to have done it…(but) I’m not really as flexible as I should be.”

The interview, led by Fox News’ Chris Wallace, was taped earlier this week, but aired Sunday morning.

It brushed upon Barack Obama’s second term, current events, and Mitt Romney’s newest grandchildren.

Mitt Romney reflected over his campaign, saying that he did not do a satisfactory job connecting with minority voters, and said that Republicans in general must strive to do better in appealing to black and Hispanic voters.

He later joked that he did better in his second run for the White House than he did the first time around – when he lost the 2008 nomination to Arizona Sen. John McCain. Regardless of his success making it as the GOP nomination, he said he won’t run for a third time.

Mitt Romney compared the experience of running for the presidency to riding a roller coaster. He told Chris Wallace: “We were on a roller coaster, exciting and thrilling, ups and downs.

“But the ride ends, and then you get off. And it’s not like, <<Oh, can’t we be on a roller coaster the rest of our life?>> It’s like, no, that ride’s over.”

Mitt Romney’s wife Ann compared the experience to the service that the Romneys have carried out within the Mormon church.

“In our church, we’re used to serving and you know, you can be in a very high position, but you recognize you’re serving. And now all of a sudden, you’re released and you’re nobody. And we’re used to that. It’s like we came and stepped forward to serve.

“And you know, the other part of it was an amazing thing, and it was really quite a lot of energy and a lot of passion and a lot of – a lot of people around us and all of a sudden, it was nothing,” she said.

“But the good news is we like each other,” Ann Romney joked.

Sharing the next phase of their lives, the couple additionally took a moment to present their family’s latest additions after becoming grandparents to 20 children on Valentine’s Day.

Mitt and Ann Romney cradled their son Craig’s newborn twins before the cameras, one seen in a pink blanket and the other in blue.

The family has kept a low profile since Mitt Romney’s concession to President Barack Obama last November. The couple has been spotted doing ordinary things, such as going to see “Twilight” and, most recently, shopping for cereal at Target.

Mitt Romney, a former Massachusetts governor, lost to President Barack Obama by a margin of 332 to 206 electoral college votes.

He spent the month after the failed White House bid in solitude at his beachfront mansion in La Jolla, near San Diego, reflecting upon the campaign.

But almost four months on it is thought Mitt Romney is ready to return to public life and political debate.

Mitt Romney is also due to address the Conservative Political Action Conference in Washington next month.
