What Is It With American Politicians And 'Corndogs'?

There seems to be some unwritten rule that American politicians must be photographed eating a corndog. To a non-American, I have to wonder what this ritual is all about.

Perhaps it is a combination of two separate 'American' political messages:

1) The 'hotdog' is truly an American cultural icon
2) The American rural Midwest and South is all about 'corn' as an agricultural product - highly subsidized.

Put the two together and you have the definitive American political-culinary expression .. a corndog. Bon appetite.
