THOSE REVELATIONS ABOUT CONGRESSIONAL INSIDER TRADING lead Jeff Carter to observe: “I now understand why campaigns have become so expensive. The net present value of beating the market by 6% annually, along with the net present value of a guaranteed government pension, cushy health benefits, and the opportunity to leverage your elected position into a lucrative full time lobbying job after ‘serving’ your country makes the spending seem minimal.” Even better, the campaign cash comes out of other people’s pockets. Win-win!
