How about something closer to home? Hilary Clinton is 7/2 favourite for next president. The rank outsider is Andrew Basiago at 500/1. What about Arnie at 150/1 or Alec Baldwin at 400/1?
To be honest, I haven't got a clue who a lot of them are. Although 20/1 for Mitt Romney seems quite high. I didn't think nominees got second chances, not since Nixon anyway.
