First you have to find a sucker that will bet you even money that Romney will beat Obama in the US presidential electoral race. It should be pretty easy, they're so convinced. Let's say you bet $100. Make sure that the person and you put the money in some type of escrow account or have a mutual friend or person hold the money so they can't weasel out.
Next you find someone or go on to a betting site and place a bet on Romney to win. Right now, you can bet about $70 to get back $110 if Romney wins.
You can not lose if you can get these bets placed. If Obama wins you net $30, if Romney wins, you net $10. Isn't being a hedge fund manager fun? I wonder if the Kochs and Adelsons and Trumps are being smart and hedging their bets.
The operative idea is that you have to find a sucker and not give him an even break. W.C. Fields would be proud too.
