Since politics came up, I thought I should mention the study which found that US senators outperform the market by 12% a year on average, and show an uncanny ability to predict big moves in stock prices. Quite good evidence that trading on inside information is pervasive among lawmakers.
I don't have a link to the study but here's what I found with a quick web search.
