Appearing on ABC's "This Week," Obama campaign senior adviser Robert Gibbs conceded Sunday that Mitt Romney had a strong performance in the presidential debate but accused him of distorting the facts.

Governor Romney had a masterful theatrical performance just this past week, but the underpinnings and foundations of that performance were fundamentally dishonest.  Look, he walked away from the central tenet of his economic theory by saying he had no idea what the president was talking about.  Ten minutes after the debate, even his own staff is walking back his answers on health care and preexisting conditions.

So, look, I don’t want to take anything away from what I think, again, was a masterful, masterful performance by Governor Romney, but I don’t think Governor Romney’s positions have changed, and fundamentally, I don’t think the campaign has changed.

He said the man who showed up at the debate was "a clone that looked a lot like Mitt Romney that had walked away from fundamentally every position that he’d taken."
