Nate Silver:
Akin Comments Could Swing Missouri Senate Race

“…It can be easy to overrate the importance of scandals in the first few days after they occur. Many voters will vote along party lines almost no matter what, and others will decide based on factors like the economy or an incumbent senator’s voting record.

Nevertheless, my view is that insensitive comments concerning rape are especially likely to be deemed inexcusable by voters, and that the swing against Mr. Akin could be larger than the average of 10 percentage points from similar events.”
