Wooing voters’ hearts through their stomachs is nothing new, especially in Iowa where presidential candidates are judged not only by their foreign policy skills but by their ability to flip a pancake.

No word on what he’s planning to feed his supporters in Ames-though he’s already got competition from Sam Brownback, who’s talked up his barbecue, and Mike Huckabee, who is air-lifting a 150-pound watermelon in from Arkansas.
