Rick Perry says he's feeling great these days—but admits that back pain was bothering him and affected his early GOP debate performances. "I would suggest to you that I was pretty fatigued. No excuses," he tells the Des Moines Register. He touched on his recent spinal fusion surgery when asked whether he should have started campaigning in Iowa earlier to get his feet wet.

He attributes his improved performance of late to being "both physically and mentally just back in the game."
