Can you tell a Democrat by their salad? A Republican by their hamburger? An Independent by their coffee? With the outcome of the US presidential election just days away, The Food Chain looks at the surprising role food has played in a campaign like no other.

Regina Ragone of Family Circle magazine tells the BBC’s Kent DePinto how a comment by Hilary Clinton started a nation-wide baking contest that has been running since 1992.
