Actually, my associate in London has put down over $13,000 (£8,700) that Romney will win; he got 3 to 1 odds so he actually got a better deal.
BTW, I have absolutely no idea how InTrade is still operating. It is illegal to gamble online, and it is also illegal for US citizens to wager on US politics. In fact, gambling on federal elections is a Secret Service offense, which is why I always reference an associate in a legal venue and jurisdiction when talking about commercial gambling odds with reference to elections.
