Larry Craig's Super Tuber

On the Congress Cooks! web page, the recipe contributed by U.S. Sen. Larry Craig, R-Idaho, is for Super Tuber -- a weiner shoved through a cored Idaho potato, then baked. Craig introduces the recipe thus:

Super Tuber is a great snack that uses one of my favorite vegetables: the Idaho potato. Of course, I suppose any type of potato could be used, but I cannot guarantee that a Super Tuber made with anything but a true Idaho potato would taste as good.
