It looks like Kerry forgot to buy a few items. He's wearing a camaflouge hat and jacket which don't quite go with the dress pants and dress shoes.
Actually, the pants are nice for duck-and-goose hunting - they have waterproof facings on the front of the leg and halfway up the back. Very useful when friendly wet Labs decide to wind back and forth against your legs. Of course, this pair have obviously just come off the hanger from Bass Pro Shop ten minutes before the photo-op. Not only perfectly clean, but the pants hems are still stiff.
But the SHOES are Sperry Topsiders - you can see the grommets for the leather thong just above the heel of his left shoe.
He must have just stepped off his Yacht for the photo-op. Where the heck are his DUCK BOOTS?????
What an idiot. I hope his feet got soaked.
