Appearing on "The Mike Huckabee Show" with his wife on Saturday, Rick Santorum said that he wished he had not called President Obama a "snob" for wanting everybody in America to go to college.
Huckabee brought up the remark in asking Santorum if he regretted anything he has said on the campaign trail during his run for the GOP nomination.
"Look, having been a candidate, we all go out there on the campaign trail, we say some things we wish we hadn't said, or we wish we'd said 'em a little differently," Huckabee said. "Is there anything out there that you would love to walk back and say, 'Well, let me do that a little differently'"?
Santorum replied: "Well, my wife, after she heard that comment, she said, 'Rick,' she said, 'His comment might have been snobbish, but that doesn't make him a snob.'"
Sometimes you say things you wish you had said a little differently, and that's certainly one of them," he continued.
Huckabee then praised the role of "the wives" on the campaign trail, who tell candidates "things nobody else will." He asked Karen Santorum to give an example of helpful advice she had given her husband.
"So much of it is just, you know, 'Be yourself, be sincere, speak from your heart -- and Rick is a very passionate man," she said. "And I love that in Rick -- very passionate. But sometimes people misinterpret that as sort of being mean. So sometimes I ask him to tone it down a little bit, and keep the balance between your passion and getting a little too fiery."
Mike Huckabee also addressed Santorum's fraught relationship with women. He said that, since the former Pennsylvania senator had married a woman with a law degree and nursing degree who has homeschooled seven children, "the last thing on earth that would ever be legitimately said about you is that you fear strong women." Karen Santorum concurred, calling Rick a "loving, passionate, devoted husband and father."
Santorum is coming off the heels of a resounding win in Saturday's Kansas caucus, which will net him most of the state's 40 delegates. Also on Saturday, Santorum fell to Mitt Romney in Wyoming's caucus.
