The best illustration of the current Presidential Campaign in the US is this painting by Mark Tansey:
Depicting Sherlock Holmes and Professor Moriarty in a deadly struggle at the edge of the precipice. One articulate and sophisticated villain v one cool dude who delivers over the fiscal cliff. Ah, one would hope we can distinguish which one is which: is Holmes = Romney or Obama? Never mind, the truth is - it's the cliff that dominates the whole set up.
