MADISON, Wis -- President Obama's senior campaign adviser David Axelrod is a former journalist who loves a good quip. And he outdid even himself the other day when he remarked that the president's new-found passion was "coming from his loins."

Repoters ate it up, dutifully tweeting and blogging the comment, even as Axelrod joked that he said "loins" just to see if the word could get into their stories.

On Monday, Axelrod was a tad more guarded in chatting with reporters during Obama's rally here.

"I promised the president no anatomical references," he said with a laugh as reporters sighed in disappointment.
