Ok, not that we need more evidence that politicians are corrupt, but I don't think many people remember the S&L scandals of the 1980s and John McCain's personal involvement with them. To their credit, the Obama campaign has put together a documentary explaining the background and McCain's involvment.
The sad thing is that the S&L crisis is in the process of repeating itself right now (on a much larger scale) with the housing bubble boom and bust. More on that later. For now, here's the video... It's definitely worth a peek.
