The bettors don’t like the odds of a Republican being elected. That is not me saying that – it is a fact
The intrade graph above is seconded by the Iowa electronic markets graph below. The short hand anaylis is that investors will pay $0.60 for a contract that will pay off $1.00 if a Democrat becomes President, but will only pay $0.40 for a contract that pays off $1.00 in the event that a Republican wins.
The edge of that graph is cut off and I can’t resize it until monday. Here is a link in the meantime.
